Question

Calculate the total surface area of a cupboard which measures 12cm by 10cm by 8cm

Options

A) 1920cm\(^2\)

B) 592cm\(^2\)

C) 296cm\(^2\)

D) 148cm\(^2\)

The correct answer is B.

Explanation:

Total surface area of a cupboard is given by the equation A = 2(lb + bh + lh) L = 12, b = 10, h = 8
A = 2((12 \(\times\) 10) + (10 \(\times\) 8) + (12 \(\times\) 8))
A = 2(120 + 80 + 96)
A = 2 \(\times\) 296
A = 592cm\(^2\)
