Question

Find the volume, lateral surface area and the total surface area of the cuboid whose dimensions are Length=15m, breadth=6m and height=9dm.

Answer 1

Given Length=15m, breadth=6m and height=9m

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

V = (15 × 6 × 0.9)

V = 81m³

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

Surface area = 2 (15 × 6 + 6 × .9 + .9 × 15)

Surface area = 2 (90 + 13.5 + 5.4)

Total Surface area = 217.8m²

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

Lateral surface area = 2 [(15 + 6) × 0.9]

Lateral surface area = 37.8 m²
