Problem

Work out the surface area of this cuboid.(image)

2

Step

Given that the height (h) the width (w), the length (l) is

6 m, 4 m, and 5 m

3

Formula

The formula for the surface area of a cuboid with height h, width w, and length l is: Area = 2(lw + lh + wh)

4

Step

Plug the values into the formula:

\$A = 2(5 \times 4 + 5 \times 6 + 4 \times 6)\$

A = 2(20 + 30 + 24)

A = 148

5

Solution

So, the surface area of this cuboid is 148 sq units.
