Math Surface Area of Prisms

Surface Area of Prisms 2.0 You can see that the highlighted surfaces are congruent. You can see that the highlighted surfaces are congruent. You can see that the highlighted surfaces are congruent. That's where the 2 comes from. Find the surface area on paper. Start with the first part of the formula, 2(lxh) then continue to check. 2(6x4)=48 start with 2( ) l hx 2(6x4)=48 Next 2( ) 2(3x4)=24 w hx 2(6x4)=48 Next 2( ) 2(3x4)=24 l w x 2(6x3)=36 2(6x4)=48 Now add the totals 48+24+36=108cm ^{2}2(3x4)=24 2(6x3)=36 What is the surface area? 216 square centimeters 384 square centimeters 432 square centimeters 512 square centimeters What is the surface area? 432 square centimeter What is the surface area? 140 square meters 220 square meters 440 square meters 500 square meters What is the surface area? 220 square meters What is the surface area? 84 square meters 468 square meters 160 square meters 168 square meters What is the surface area? 168 square meters Look at the figure and think about how many sides it has. Use paper and pencil to total the surface area. On a triangular prism you can add up the surface areas if you know them. Each triangle has an area of 6 square meters (sq m). Each triangular surface has an area of 10 square meters (sq m). What is the surface area of this figure? 42 sq m 36 sq m 26 sq m 16 sq m On a triangular prism you can add up the surface areas if you know them. Each triangle has an area of 6 square meters (sq m). Each triangular surface has an area of 10 square meters (sq m). What is the surface area of this figure? 42 sq m On a triangular prism you can add up the surface areas if you know them. 30+12= 42 10 +10+10 = 30 two triangles three rectangles 6+6=12 |
