Question

17. The length, breadth and height of a cuboid are in the ratio of 6:4:3. If the total surface area
is 832 cm, find the volume of the cuboid.
​

Answer 1

Answer:

Step-by-step explanation:

let dimensions be 6x, 4x and 3x

A/Q-

Total surface area of cuboid = 2(lb+bh+hl)

                                 832 cm²  = 2( 6x * 4x + 4x * 3x + 3x * 6x )

                                 832 cm²  = 2 ( 24x² + 12x² + 18x² )

                                 832 cm²  = 2 × 54x²

                                 832 cm²  = 108x²

you can solve now
