Question

A tank 1.1 m long, 60 cm wide and 40 cm high is painted with blue paint.

What is the total surface area coated with blue paint?

Answer 1

Answer: 26800 square centimeters

Explanation:

Converting all the dimensions to cm, we get the tank is 110 cm long, 60 cm wide, and 40 cm high.

Using the formula for the surface area of a rectangular prism yields
`2(110 \cdot 60+110 \cdot 40+60 \cdot 40)=26800` square centimeters.
