The number of planks of dimensions(4 m×5 m×2m)that can be stored in a pit which is 40 m long, 12 m wide and 16 m deep,is(a) 190 (b) 192 (c) 184 (d) 180
The volume of pit = 40 m × 12 m× 16m=7680m3
Volume of planks = 4 m×5 m× 2 = 40m3
Hence, number of planls = 768040 = 192
192 planks can be stored in a pit.
