Math 11 Apprenticeship and Workplace Unit 3 Surface

Math 11 Apprenticeship and Workplace Unit 3 – Surface Area, Volume and Capacity 3. 1 – Surface Area of Prisms Finding the Area of All Sides

• Net • Rectangular Prism • Two-dimensional pattern that can be folded to form a threedimensional shape. • A three-dimensional shape with ends that are congruent rectangles and with sides that are parallelograms

• Prism • Contains two parallel polygons that are congruent • Congruent Polygons • Have the same shape and size • Have sides and angles in the same position • Each parallel face is called a base • Faces connecting bases are called lateral faces • If the faces are perpendicular to the bases, then the prism is a right prism

• Surface Area • The area required to cover a three-dimensional shape. Units of measurement are squared (cm²) • Base • One of the parallel faces of a prism (top and bottom) Lateral Face • The face that connects the bases of a prism

Useful Formulas • Area of a Rectangle • Area of a Triangle • Area of a Circle •
