Question

If dimensions of a cuboid are in the ratio 1:2:3 and it's total surface area is 88m2 the it's volume is​

Answer 1

Answer:

48.

Step-by-step explanation:

let x be a unit of measure

therefore ratio becomes x:2x3x

TSA of a cuboid = 88

2(lb+bh+lh) = 88

2(x*2x + 2x*3x + x*3x) = 88

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

11x2 = 44

x2 = 4

x = 2

then sides : 2,4,6

volume = lbh = 2*4*6 = 48
