2. Finding the Surface Area of a Regular Pyramid
Step 1:
Find the dimensions of the sides.
Step 2:
Substitute and multiply.
Step 3:
Add.
Step 4:
Write the units.
Surface Area = 4[½(side length x base side)] + (base side x base side)
Step 1:
Side length is 5
Base side is 6
5 in
Step 2:
Substitute and
multiply
6 in
Area = 4[½(5 x 6)] + (6 x 6)
Area = 4[½(30)] + 36
Area = 4(15) + 36
Area =
Area = 96
Step 3:
Add
You multiply by 4 because there are 4 triangles.
Step 4:
Write the units
in 2
