Question

Find the surface area of sphere whose volume is 5887.32cm cube

Answer 1

Edge of the cubical tank = 1.5 m = 150 cm (= a)

So,           surface area of the tank = 5 × 150 × 150 cm2

Area of each square tile = side × side = 25 × 25 cm2

So, the number of tiles required = Surface area of tank/Area of each tile = 5 x 150 x 150/25 x 25 =180

Cost of 1 dozen tiles, i.e., cost of 12 tiles = Rs 360

Therefore, cost of one tile = Rs 360/12= Rs 30

So, the cost of 180 tiles = 180 × Rs 30 = Rs 5400
