Answer 2

Jeff has a block that is 2 inches wide, 3 inches long, and 2 inches tall. Jeff decides to build a tower that is built using three of these blocks. What is the volume of his tower?

36in2
20in2
24in2
21in2

Answer 3

The volume of one block is given by:
2 inches x 3 inches x 2 inches = 12 cubic inches
Since Jeff is using three of these blocks to build the tower, the total volume of the tower is:
3 x 12 cubic inches = 36 cubic inches
Therefore, the answer is 36in2.

Answer 4

A dump truck whose bed is 8 feet long, 5 feet wide, and 4 feet high is delivering gravel to a construction site. How many trips must the dump truck make to the construction site to deliver 400 cubic feet of gravel?

Question 14 options:

1)

1 trip

2)

2 trips

3)

3 trips

4)

4 trips

Answer 5

The capacity of the dump truck's bed is given by the product of its length, width, and height, which is:

8 feet x 5 feet x 4 feet = 160 cubic feet

To deliver 400 cubic feet of gravel, the dump truck must make:

400 cubic feet ÷ 160 cubic feet/trip = 2.5 trips

However, since the dump truck cannot make a fraction of a trip, it must make 3 trips to deliver 400 cubic feet of gravel. Therefore, the answer is 3 trips.
