Question

A cement block is in the shape of a rectangular prism that measures 4.5 feet by 7.25 feet by 6.5 feet. The entire block must be painted.

How many square feet will be painted?

Answer 1

Since A=l*w*h,

A=4.5*7.25*6.5
A=212.0625

A=212.0 feet squared is the answer.

Answer 2

Answer: 152.75 square feet will be painted.

Explanation:

Since we have given that

Length of prism = 4.5 feet

Width of prism = 7.25 feet

Height of prism = 6.5 feet

As we know that the base of prism is rectangle.

So, Area of rectangular prism is given by

Perimeter of base × height

`=2(l+b)* h\\\\=2(4.5+7.25)* 6.5\\\\=152.75\ ft^2`

Hence, 152.75 square feet will be painted.
