Volume and Surface Area

Prisms and Pyramids

Surface Area

Surface Area is the Area of all the sides of the 3D figure added together.

Rectangular Prism

Has 6 sides made of rectangles, To find surface area do the following math. $\left(l\cdot w\cdot2\right)+\left(l\cdot h\cdot2\right)+\left(w\cdot h\cdot2\right)$  

To find the Volume use the following formula.  $l\cdot w\cdot h$  

Triangluar Prism

Has 5 sides, 2 triangles and 3 rectangles. To find the surface area of do the following math. $\left(b\cdot h\right)+\left(l\cdot b\right)+\left(w\cdot b\right)+\left(h\cdot l\right)$  

To find Volume use the formula  $\left(b\cdot h\div2\right)\cdot l$  

Rectangular Pyramid

Has 5 sides, 4 triangles and 1 rectangle. To find surface are do the following math. $\left(l\cdot w\right)+\left(l\cdot h\right)+\left(w\cdot h\right)$  

To find Volume use the following formula. $l\cdot w\cdot h\div3$
