Question

11.The edges of a cuboid are in the ratio 1:2:3and its surface area is
88sq.cm, the volume of the cuboid is
​

Answer 1

Answer:

Ratio of edges of cuboid = 1 : 2 : 3

Let, l = x, b = 2x, h = 3x

Surface area = 88cm2

2(lb+bh+hl)=88

2(2x2+6x2+3x2)=88

11x2=44

x2=4

x=2

∴l=2cm, b=4cm, h=6cm

∴ Volume=lbh

=2×4×6

=48cm3
