Question

Simple maths question... i just don't understand how to do it

Answer 1

Answer:

Cut the prism into 2 parts like the picture below

Name the upper part A, and the lower part B

Calculate the volume of part A:

12 - 8 = 4 cm

4 * 5 * 6 = 120 $cm^{3}$

Calculate the volume of part B:

15 * 8 * 6 = 720 $cm^{3}$

Volume of the whole prism:

Volume of part A + volume of part B

120 + 720 = 840 $cm^{3}$
