Question

The diagram shows a cuboid 4cm, 5cm and 9cm what is the surface area of the cuboid?

Answer 1

given:

length= 9 cm

width= 5 cm

height= 4 cm

to find:

the surface area of the given cuboid.

solution:

`s.a = 2(lb + bh + lh)`

`s.a = 2((9 * 5) + (5 * 4) + (9 * 4))`

`s.a = 2(45 + 20 + 36)`

`s.a = 2 * 101`

`s.a = 202 \: {cm}^(2)`

therefore, the surface area of the given cuboid is 202 square centimeters.
