Respuesta :

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.
