The height of a rectangular prism is 3 in ... The perimeter is 88 in. (4 in. wide and 11 in. long). What is the value of the base?

The base of a rectangular prism (b) = 41 in.

Step-by-step explanation:

Given,

The height of a rectangular prism (h) = 3 in and

The perimeter of a rectangular prism = 88 in

To find, the base of a rectangular prism (b) = ?

We know that,

The perimeter of a rectangular prism = 2l + 2b or 2b + 2h or 2h + 2l

∴ 2b + 2 (3) = 88

⇒ 2b = 88 - 6

⇒ 2b = 82

⇒ b = 41 in

Thus, the base of a rectangular prism (b) = 41 in.
