### Question

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

A) 1920cm2

B) 592cm2

C) 296cm2

D) 148cm2

### Explanation:

Total surfaced area of a cupboard = lb + lh + bh
l = length h = height b = base
l = 12cm h = 10cm b = 8cm
T.S.A $$= (12 \times 8 \times 12 \times 10 + 8 \times 10)cm^\\= (96 + 120 + 80)cm^2 = 296cm^2$$

## Dicussion (1)

• Total surfaced area of a cupboard = lb + lh + bh
l = length h = height b = base
l = 12cm h = 10cm b = 8cm
T.S.A $$= (12 \times 8 \times 12 \times 10 + 8 \times 10)cm^\\= (96 + 120 + 80)cm^2 = 296cm^2$$
