Jamie is trying to work out the surface area of the cuboid below. Spot any mistakes and write the correct answer.

umka21 [38]

Step-by-step explanation:

The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.

The formula for the surface area of the cuboid is as follows :

$A=2(lb+bh+hl)$

We have,

b = 9 cm, l = 7 cm and h = 5 cm

So,

$A=2(9\times 7+9\times 5+7\times 5)\\\\A=2\times 143\\\\A=286\ cm^2$

Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.
