Question

how many planks of dimensions (5m×25cm×10cm) can be stored in a pit which is 40m long 6m wide and 80cm deep​

Answer 1

Answer:

number of plank needed to fill the pit is 153600

Step-by-step explanation:

volume of a cuboid = L x B x H

L = 40 m

B = 6 m

H = 80 m

so, = 40 x 6 x 80 = 19200 m³

Number of planks = volume of plank x number of plank(n) = 19200

volume of plank =  L x B x H

                           = 5 x 0.25 x 0.1 m

                           = 0.125 m³

now

    = 0.125 x n = 19200

    = n = 19200/0.125

    = n = 153600

number of plank needed to fill the pit is 153600
