Question

The dimensions of a cuboid are equal to half the dimensions of another cuboid. Find the ratio of the (i) Volume (ii) Surface area of the cuboid​

Answer 1

Answer:

volume of 1st cuboid = lbh

volume of second cuboid = l/2*b/2*h/2 = lbh /8

so ratio of 1st volume to 2nd vol = 8:1

now

surface area of 1st = 2(lb + bh + hl)

surface area of 2nd = 2 ( lb/4 + bh/4 +hl/4)

ratio = 4:1
