Question

16 cubical tin boxes with edge 8 cm are to be
made. Find the cost of tin sheet required at the
rate of 200 per m².​

Answer 1

Answer:

₹122.28

Step-by-step explanation:

Total surface area of cube = 6 × (side)²

Given, side = 8 cm

=> T.S.A. of 1 cube = 6 × (8)² = 6 × 64 cm² = 384 cm²

T.S.A. of 16 cubes = (384 × 16) cm² = 6114 cm²

6114 cm² = (6114/10000) m² = 0.6114 m²

Cost of tin sheet per m² = ₹200

Total cost = ₹200 × 0.6114 = ₹122.28
