The following figure shows a solid made up of identical cubes.If the total surface area of the solid is 1620 cm2.What is the base area of one side of the cube?

Question

I dun understand.

Answer 1

There is no way of solving this problem without the picture, however, just trying to help you

 

Is it possible there are 4 identical cubes in the figure? (Since you may be unable to post the diagram/figure.)

 

In any case, you solve problems like this by simplifying the question.

Solve for one of the cubes and apply that for all the cubes.

 

Let's assume the cubes are connected by their faces; only 5 faces of each cube is accessible. There are 20 faces total, (4)(5)=20.

 

Each face, therefore, has an area of 81cm², 1620cm² /20= 81cm² (the base area of each cube)

 

This may possibly be the answer.
