464760cm3

Step-by-step explanation:

First we have to find the area of the box, and since it has a square base, the box is a cube with all sides equal

A cube has six sides, but the top side is open, so this box will have 5 sides

We are given the material in cm2 units which is also the unit for area, so we divide the value by the number of sides to get the area of each of the 5 sides

30000/5 = 6000cm2

So finding the volume of a cube is Length x beadth x height, which have the same values, because all sides in a cube are equal

Area = 6000cm2

To find the Length( same as height) we find the root of the Area

Root6000 = 77.46

Length = height = 77.46cm

Volume = Length x Breadth x height = Area x height = 6000 x 77.46 = 464760m3
