Question

# The surface area of a cuboid is 3600 sq m. If its dimensions are in the ratio 4:2:2, find its volume.

- 430 cu m
- 421 cu m
- 432 cu m
- 411 cu m

## The correct answer is: 432 cu m

### let the dimensions of the cuboid be 4x,2x,2x.

surface area of cuboid

=2[4x × 2x + 2x × 2x + 2x × 4x]

=2[8x^{2 }+ 4x^{2} + 8x^{2}]

=2[20x^{2}]

=40x^{2}

According to the question,

40x^{2}=3600

X^{2 }=3600/40

X^{2}=9

X=(9)^{}

X=3

Dimensions =12m , 6m , 6m

Volume= 12×6×6

Volume= 432 cu m
