Question

the dimensions of a closed cuboidal packing case are in ratio 5:4:3 if the total surface area is 0.0188 suare metre find the dimensions of the cuboid

Answer 1

Answer:6:3:2

Step-by-step explanation:

As you can see, there are 22 portions, as there’s two of each size of side. Divide the total surface area by it. You get 256.

256 is the size of a 1 by 1 unit square. Take its square root to get the length of one unit, which is 16 cm.

Multiply by the ratio to get 16*32*48. Plug those numbers into a calculator to get 24,576.
