Surface Area of Rectangular Prisms Find the surface area of each rectangular prism. 7. GIFTS Minh is covering a necklace box with gift wrap. The necklace box is 15 centimeters long, 8 centimeters wide, and 2 centimeters high. What is the minimum surface area of the paper that will cover the necklace box? 332 cm³ 8. ESTIMATION Alicia estimates that the surface area of a rectangular prism with a length of 11 meters, a width of 5.6 meters, and a height of 7.2 meters is about 334 cubic meters. Is her estimate reasonable? Explain your reasoning. No; 5.6 rounds to 6, so surface area is: 2(67) + 2(6-11) +2(711) 370 9. BLOCKS Find the surface area of each block. Which block has the greater surface area? Does the same block have a greater volume? Explain. Block A: 94 in²; Block B: 104 in²; Block B has a greater surface area. No, the volumes of Blocks A and B are the same, 60 in³. Surface Area of Triangular Prisms Find the surface area of each triangular prism. Round to the nearest tenth if necessary. 5. One foam block on the playground at Teeny Tots Preschool is a triangular prism. About how much material is used to cover the block? 543 in² 13.4 in 6 in 12 in. 15 in 6. The box for the jungle animal figurines is in the shape of a triangular prism. What is the surface area of the box? 7. The storage box for a flag is in the shape of a triangular prism.
