Q1. A rectangular field 30 m long and 20 m broad. How much deep it should be dug so that from the earth taken out, a platform can be formed which is 8 m long, 5.5 m broad and 1.5 m high. Geometric Measurement
Answer: 11 cm
Explanation: Volume of platform = 8×5.5×1.5 = 66 m³; field area = 30×20 = 600 m². Depth = 66/600 = 0.11 m = 11 cm.
