Answer:

Option (3) is correct.

The surface area of a rectangular prism of given dimension is 170 square inches.

Explanation:

Given : a rectangular prism whose base is 5 inches by 6 inches and whose height is 5 inches.

We have to find the surface area of a rectangular prism of given dimension.

Since a rectangular prism whose base is 5 inches by 6 inches

That is length (l)= 5 inches

Width (w) = 6 inches

and height (h) = 5 inches.

Also .
$\text{surface area of a rectangular prism}=2(lw+wh+hl)$

Substitute, we have,

$\text{surface area of a rectangular prism}=2(5\cdot 6+5\cdot 5+5\cdot 6)$

simplify , we have,

surface area of a rectangular prism = 170 inches²

Thus, the surface area of a rectangular prism of given dimension is 170 square inches
