Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 11

b. Find the surface area of the juice box. Show your work.
Answer:
SA = 2(l.w + l.h + w.h)
SA = 2(3 in. . 2 in. + 3 in. . 4 in. + 2 in. . 4 in.)
SA = 2(6 in2 + 12 in2 + 8 in2)
SA = 2(26 in2)
SA = 52 in2

c. Find the volume of the juice box. Show your work.
Answer:
V = l.w.h
V = 3 in. . 2 in. . 4 in.
V = 24 in2

Question 2.
The Cubic Crystal Company has a new Crystal Cube they want to sell. The packaging manager insists that the cubes be arranged to form a rectangular prism and that the package be designed to hold the Crystal Cubes exactly, with no leftover packaging. Each Crystal Cube measures 1 in. × 1 in. × 1 in. There are 24 Crystal Cubes to be sold in a box.

a. What are the dimensions of the possible box designs in inches?
Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 3
Answer:

Height Width Length
1 in 1 in 24 in
1 in 2 in 12 in
1 in 3 in 8 in
1 in 4 in 6 in
2 in 2 in 6 in
2 in 3 in 4 in

b. Which Crystal Cube box design will use the least amount of cardboard for packaging? Justify your answer as completely as you can.

Answer:
Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 13
The minimum surface area is found to be on the 2 in × 3 in × 4 in box. That box needs the least amount of cardboard.

c. Another type of cube is the Mini Crystal Cube, which has an edge length of inch. What is the volume in cubic inches of one Mini Crystal Cube? Show your work.
Answer:
V = l.w.h
V = \(\frac{3}{4}\) in . \(\frac{3}{4}\) in . \(\frac{3}{4}\) in
V = \(\frac{27}{64}\) in3

Question 4.
Which box below has the larger surface area?

Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 7
Answer:
SA = 2(l.w + l.h + w.h)
SA = 2(5 in. . 2 in. + 5 in. . 3in. + 2 in. . 3 in.)
SA = 2(10 in2. + 15 in2. + 6 in2.)
SA = 2(31 in2.)
SA = 62 in2.

SA = 2(l.w + l.h + w.h)
SA = 2(10 in. . 1 in. + 10 in. 3 in. + 1 in. . 3 in.)
SA = 2(10 in2 + 30 in2. + 3 in2.)
SA = 2(43 in2.)
SA = 86 in2
This box has the larger surface area.

Question 5.

a. Draw a polygon in the coordinate plane using the given coordinates.

(4, -4)
(6, -2)
(8, -6)
Answer:
Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 15

b. Calculate the area of the polygon.
Answer:
Area of Square:
A = l.w or S2
A = 4 u. 4 u or (4 u)2
A = 16 u2

Area of Triangle 1:
A = \(\frac{1}{2}\) bh
A = \(\frac{1}{2}\) 2 u . 2u
A = 2 u2

Area of Triangle 2:
A = \(\frac{1}{2}\) bh
A = \(\frac{1}{2}\) 2 u . 4 u
A = 4 u2

Area of Triangle 3:
A = \(\frac{1}{2}\) bh
A = \(\frac{1}{2}\) . 2 u . 4 u
A = 4 u2

Area of Triangle 4 = 16 u2 – 2 u2 – 4 u2 – 4 u2 = 6 u2

Question 6.
Eaglecrest Elementary School is creating a vegetable garden at the school.

a. What is the area of the garden?
Eureka Math Grade 6 Module 5 End of Module Assessment Answer Key 9
Answer:
A = b.h
A = 25 ft . 6 ft
A = 150 ft2

b. After more discussion, Eaglecrest decided to change the location of the garden so that the vegetables can get more sunlight. Below is the new garden.

In which garden can eagle crest students plant more vegetables? Explain your reasoning.
Answer:
A = \(\frac{1}{2}\) bh
A = \(\frac{1}{2}\)(7 ft. . 28 ft.)
A = \(\frac{1}{2}\) (194 ft2)
A = 98 ft2

The students of Eaglecrest can plant more vegetables in original garden in the shape of a parallelogram. It has a larger area than the triangular prism.
