Question
Find the volume, lateral surface area and the total surface area of the cuboid whose dimensions are:
$Length = 22cm, breadth = 12cm and height = 7.5cm.$
$Length = 22cm, breadth = 12cm and height = 7.5cm.$
✓
Answer
Length of cuboid (l) = 22cm.
Breadth (b) = 12cm
and height (h) = 7.5cm.
- Volume $= lbh =22 \times 12 \times 7.5 cm^3$
- Lateral surface area = $=2(l+ b ) \times h$
$=2 \times 34 \times 7.5=510 cm^2$
- Total surface area = $=2[ lb + bh + hl ]$
$= 2 \times 34 \times 7.5=510 cm^2$
$= 2 \times 519=1038 cm^2$
