I need help on this can someone please help me.

Simple, to find the volume of a rectangular prism, just multiply the length by the height by the width. Like this:

3 x 4 x 5

The answer is 60.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
