A cuboid has total surface area of 50 m2 and lateral surface area is 30 m2. Find the area of its base.

Answer:

Given details are,

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
