Question

How many wooden cubical blocks of side 25cm can be cut from a log of wood ofsize, length = 3m, width = 75cm and height = 50cm, assuming there is no wastage of wood.[3]Q6.

Answer 1

the length of the side of the cubical block = 25 cm

volume of the one cubical block = 25*25*25 cubic cm

let the required number of blocks be n.

therefore the volume of the n cubical blocks = volume of wood

n*253=300*75*50

n=12*3*2=72

thus required number of blocks is 72.

hope this helps you
