Question

The volume of a rectangular prism with a square base and a height of $10ft$ is $160cuft$. What is the side length of the base of the rectangular prism?

• A. $10ft$
• B. $16ft$
• C. $4ft$
• D. $8ft$

Answer 1

The correct option is C $4ft$

Height of the rectangular prism: $10ft$
Volume of the rectangular prism: $160cuft$
Since the base is a square, its length and width are equal.
We know,
Volume of a rectangular prism = length $\times$ width $\times$ height
$160=$ length $\times$ width $\times 10$
$16=$ length $\times$ length
$4\times 4=$ length $\times$ length

So, length $=4ft$
​​​​​​
Hence, the length of the base of the rectangular prism is $4ft.$
