The face has 6 cubes...there are 4 rows of 6 cubes 6 * 4 = 24 cubes

Second one:

There are TWO faces that are 10 x 5 2 x (10 x 5) in^2

Volume is the number of little cubes (with sides 1*1*1 unit) that fit into the big shape.

The first one has the cubes drawn on it.

Can you see thast there are 6 cubes in the front row ?

And then there are 4 rows going back

So that must be 6+6+6+6 = 24 unit cubes or 24 cubic units

You could have got this by saying

2*3 * 4 = 24
