Prism a has a volume of 54in^3 and a similar prism b has a volume if 16in^3. if prism a has a surface area of 90in^2, find the surface area of prism b.

Volume is the amount of 3-dimensional space an object occupies. Volume is measured in cubic units.

For example, the rectangular prism below has a volume of 181818 cubic units because it is made up of 181818 unit cubes.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
