Question

A container shape as a rectangular prism can hold 840 wooden cube blocks with edge lengths of 1/2 feet. What is the volume of the container?

Answer 1

we know that
volume of one wooden cube blocks=(1/2)³=1/8 ft³

volume rectangular prism=840*(1/8)=105 ft³

the answer is 105 ft³

Answer 2

The first thing we should know is that the volume of a cube by definition is:
V = L ^ 3
Where:
L: side.
We have then that the volume of a cube is:
V = (1/2) ^ 3
V = 1/8
Then, the prism volume is:
Vtotal = 840 * V
Vtotal = 840 * (1/8)
Vtotal 105 feet ^ 3
Answer:
the volume of the prism is:
Vtotal 105 feet ^ 3
