Question

A box in the shape of cuboid has the total surface area of 70 cm square and lateral surface area of 35m square. Find the area of its base

Answer 1

Answer:

Step-by-step explanation:

Total Surface Area = 2(lb+bh+hl)

70/2 = lb+bh+hl

3500 = lb+bh+hl - (1)

Lateral Surface Area = 35 m

2h(l+b) = 3500cm

lh+bh = 3500/2

lh+bh = 1750 cm - (2)

From eq. (1) &(2) :-

3500 = 1750+lb

1750 = lb

1750cm = Area of Base
