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?

Enter your answer in the box.

Answer 1

I am pretty sure that if you are looking for perimeter there should only be two sets of numbers but if you are looking for area than the answer would be 212.0625 

Answer 2

218 square feet will be painted.

Explanation:

A cement block is in the shape of a rectangular prism that measures 4.5 feet by 7.25 feet by 6.5 feet.

Rectangular prism is a cuboid shape. We have to find the total surface area of cuboid.

Formula:

`\text{Total surface area}=2(lb+bh+lh)`

where, l=4.5 feet, b=7.25 feet and h=6.5 feet .

`\text{Total surface area}=2(4.5* 7.25+7.25* 6.5 +6.5* 4.5)`

`\text{Total surface area}=218\text{ ft}^2`

We will paint entire block of cement i.e must be equal to 218 square feet.

Hence, 218 square feet will be painted.
