Question

find the volume of the rectangular prism. which expression can be used to find the volume in cubic feet? 2×4×8 which expression shows another way to find the volume in cubic feet? 6 + 8 6×8 8 + 8 8×8

Explanation:

Step1: Recall volume formula

The volume formula for a rectangular prism is $V = l\times w\times h$, where $l$ is length, $w$ is width and $h$ is height. Here $l = 2$, $w = 4$ and $h=8$, so $V=2\times4\times8$.

Step2: Rearrange factors

We can also calculate the base - area first. The base with sides 2 and 4 has area $A = 2\times4=6$. Then multiply by the height 8, so another way is $6\times8$.

Answer:

The first question: $2\times4\times8$
The second question: $6\times8$
