Area of 3D Shapes Formula
| Shape | Surface area | Terms |
|---|---|---|
| Rectangular prism | 2(wl+hl+hw) | l = length w = width h = height |
| Cylinder | 2πr(r + h) | r = radius of circular base h = height of the cylinder |
| Cone | πr(r + l) | r = radius of circular base l = slant height |
| Sphere | 4πr2 | r = radius of sphere |

| Cube | V = a3 | a = Length of edge or side |
How do you figure out the volume of a shape?
You can work out the volume of a shape by multiplying height × width × depth.
What is the formula for irregular figures?
Area of the given irregular shape = Area of the rectangle ‘P’ + Area of the semicircle ‘Q’ + Area of the triangle ‘R’ + Area of the rectangle ‘S’. ⇒ Area of the given irregular shape = 48 + 39.25 + 24 + 48 = 159.25 square units. Therefore, the area of the given irregular shape is 159.25 square units.
