Question

the dimensions of a cuboid are in the ratio 1 ratio 2 ratio 3 ratio and its volume is 384 cubic metre find its dimensions and surface area​

Answer 1

Answer:

4m and 8m and 12m

Step-by-step explanation:

volume of a cuboid is lbh where l is length b is breath h is height. so let the l.b.h be 1x.2x.3x

so 6x^3=384

therefore x is 4

l is 1x which is 4

b is 2x which is 8

h is 3x which is 12

surface area is 2 (lb + bh + lh)

so from this surface area is 2*176 which is 352
