Edges of a cuboid are in the ratio 1 : 2 : 3. Its surface area is 88 $$cm^2$$. What is its volume?
let edges of cuboid be 1x, 2x, 3x
given surface area=88$$cm^{2}$$
total surface area of cuboid =2(lw+wh+hl)
88=2(1x*2x+2x*3x+3x*1x)
88=2*(2$$x^{2}$$+6$$x^{2}$$+3$$x^{2}$$)
88=2*11$$x^{2}$$
88=22$$x^{2}$$
$$x^{2}$$=$$\frac{88}{22}$$
$$x^{2}$$=4
x=2
dimension of cuboid are 2cm,4cm and 6cm
volume of cuboid = l*b*h
=2*4*6
=48$$cm^{3}$$
