What is the missing dimension of a rectangle or prism with the following dimensions and volume? length 3 cm width 5 cm volume 45 cm3 height? me find the height.

You got the volume so the formula for finding a rectangular prism is l*w*h=x. l stands for length, w stands for width, h stand for height, and x stands for the total volume. Put the numbers in the formula so do 3*5*l=45 multiply the 3 and 5 and you will get 15*l=45 and divide by 15 on both sides (use a calculator if you can't do it in your head) and the answer should be 3.

Google it that might work

Idon’t feel like doing the math but you need to do 2.24 divided by 7
