Question

there are three cubes their volumes are in the ratio 2:3:4 the sum of the volumes of the cubes is 19773 cm find the volume of each cube

Answer 1

let the no.be 2x,3x,4x
a/q=volume = 6x(side)2

Answer 2

Let the volumes be 2x, 3x, and 4x.

Sum of volumes

= 2x + 3x + 4x = 19773

= 9x = 19773

x = 19773 ÷ 9 = 2197

Volume of first cube = 2x = 2 × 2197 = 4394 cm³

Volume of second cube = 3x = 3 × 2197 = 6591 cm³

Volume of third cube = 4x = 4 × 2197 = 8788 cm³
