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.

Answer 1

Given Length=22cm, breadth=12cm and height=7.5cm

We know that volume of cuboid= length × breadth × height

V = (22 × 12 × 7.5)

V = 1980cm³

We know that total surface area of cuboid= 2(l b + b h + h l)

Surface area = 2 (22 × 12 + 12 × 7.5 + 7.5 × 22)

Surface area = 2 (264 + 165 + 90)

Total Surface area = 1038cm²

We know that lateral area of cuboid= 2 [(l + b) × h]

Lateral surface area = 2 [(22 + 12) × 7.5]

Lateral surface area = 510 cm²
