Surface Area & Volume of Prisms
To determine the surface area of prisms find the area of each side
To determine the volume of prisms use the formula
Volume of a Prism: V = B x hB = Area of base
h = height

Surface Area & Volume of Prisms
Example 1: Find the surface area of the
following prism.
Area of Top & Bottom
A = 2(l x w)
A = 2(3 x 4)
A = 24 cm2
Area of Sides
A = 2(l x w)
A = 2(4 x 12)
A = 96 cm2
Area of Front & Back
A = 2(l x w)
A = 2(3 x 12)A = 72 cm2

Surface Area & Volume of Prisms
Area of Rectangular Prism
Add up the areas of all the sides
A = 72 + 24 + 96
A = 192 cm2

Surface Area & Volume of Prisms
Area of Sides
Side 1 Side 2
A = (l x w) A = (l x w)
A = (3 x 5) A = (4 x 5)
A = 15 m2 A = 20 m2
Side 3
A = (l x w)
A = (2 x 5)
A = 10 m2
Area of Triangular Prism
A = 10 + 15 + 20 + 6
A = 51 m2
