Please help if your nice :)

sorry it’s long.Given that the rectangular prism with length l = 2..6 yards.

The width of the rectangular prism is 3.5 yards.

The height of the prism is h yards.

We need to determine the simplified expression for the surface area of the rectangular prism.

We also need to determine the surface area of the prism if the height is 4 yards.

Expression for the surface area of the prism:

The surface area of the rectangular prism can be determined using the formula,

Substituting l = 2.6, w = 3.5, h = h, we get;

Thus, the simplified expression for the surface area of the prism is

Surface area of the prism:

Now, we shall determine the surface area of the prism if the height is 4 yards.

Substituting the value h = 4 in the expression , we have;

Thus, the surface area of the rectangular prism is 67 square yards.
