Answer:
The height of the prism is 
Step-by-step explanation:
we know that
The volume of the rectangular prism is equal to

In this problem we have



substitute in the formula and solve for H

![H=5,376/[(14)(16)]](https://tex.z-dn.net/?f=H%3D5%2C376%2F%5B%2814%29%2816%29%5D)

7 mm x 9mm x 12mm = 756mm
To get this answer you have to multiply 9 and 12 which would be 108. Then you have to divide 108 on both sides to get mm by itself. 756 divided by 108 is 7 which is the answer!
Area of trapezium= 1/2 × (a+b) × h
= 1/2 × (12 + 8) × 8
= 1/2 × 20 × 8
= 10 × 8
= 80 cm^3

Answer:
20
Step-by-step explanation:
you would take 8 times 2.5 to figure that out
1. Distribute
1/125 x 5n - 1/125
2. Simplify 1/125 x 5n to n/25
n/25 - 1/125
