Question

Acuboid has total surface area of 50 m’and lateral surface area is 30 m². Find the area of its base.​

Answer 1

Answer:

Total surface area of cuboid = 50 m2

Lateral surface area of cuboid = 30 m2

Total Surface area = 2 (surface area of base) + (surface area of 4 walls)

50 = 2 (surface area of base) + (lateral surface area)

50 = 2 (surface area of base) + 30

50 – 30 = 2 (surface area of base)

20 = 2 (surface area of base)

Surface area of base = 20/2

= 10 m2

∴ Area of base is 10m2
