From your previous lesson, you have learned the formulas in finding the surface area of different solid/spatial figures, also known as three dimensional figures, such as cube, prism,
pyramid, cone, cylinder and sphere. The table below summarizes the formulas in finding the surface
area of the following solid/spatial figures.
Formulas in Finding the Surface Area
1. Cube
= 62
2. Rectangular Prism = 2ℎ + 2 + 2ℎ
3. Pyramid
Square Pyramid:
SA = 4 ( 1
2s.h ) + 2
Rectangular Pyramid:
SA = lw + s1w + s2l
4. Cone
SA = πr2 + πrh
5. Cylinder
SA = 2πrh + 2πr2
6. Sphere
SA = 4πr2
Find the surface area of the following.
