Guided Practice 1 The figure is a cube. Find the surface area.
The figure is a triangular prism. Find the surface area. Guided Practice 2
The figure is a pyramid with a square base. Find the surface area. Guided Practice 3
The figure is a pyramid with a triangular base. Find the surface area. Guided Practice 4
Conclusion 1.Surface Area of a solid means the amount of space on the surface. 2.It is a measure of area, thus the units are square units. 3.We can find surface area of prisms and pyramids by finding the area of each face and adding. 4.A net can be helpful to use.
Assignment Find the surface area of solids. 1.Solve the practice exercises on the attached page. Show all work.
