3. Formulas: Rectangle A = b x h P = 2 x (b + h) A t = 2Lh + 2 Ll + 2hl Square A = s 2 P = 4s Remember! b h s s

4. V = l x w x h l = length w = width h = height  To calculate the volume of a rectangular prism, we use the formula V = l x w x h or V=lwh  What do you notice about the formula for volume??? Volume of a Rectangular Prism l w h

5. To find the volume of a rectagular prism: Step 1: find the values for length, width and height for the rectangular prism Step 2: substitute the values for length, width and height in the equation for volume. Step 3: solve. V=lwh V = 9 x 6.5 x 1.6 V = 93.6 cm 3 Volume of a Rectangular Prism 9,0 cm 6.5 cm 1.6 cm
