VOLUME OF SOLIDS
VOLUME OF PRISMS V = Area of Base x Height V = 6 cm 8 cm 10 cm All measurements must be in the same UNIT before doing ANY calculations !
Example #2 Find the volume of a prism that is 15 cm high and has a pentagonal base. The area of the pentagon is 105 cm 2. Give your answer in cubic centimeters. Height = Area of base = Volume = Area of base X Height Volume =
How to find height when you know volume and area of the base. Volume = Area of Base X Height Height = Volume Area of Base Example: Prism has a volume of 2400 cm 3 and an area of base of 120cm 2 What is its height? Height = Volume A base H = V= 2400 cm 3 A base = 120 cm 2
Area base = Volume Height Find the area of the base of a prism That has a volume of 300 cm 3 and a height of 5 cm. Area base = How to find area of base when you know volume and height. V= 300 cm 3
Volume of Cylinders Volume = Area of Base X Height Volume = πr 2 X Height Volume = Volume = (exact) Volume = (rounded) Remember to ALWAYS work in ONE unit. H = 10cm d= 4 cm
