Surface Area= Area of the 2 triangles + Area of the 3 rectangles
Lateral Area= Area of the 3 rectangles
S= (28cm)(12cm) + 2 (48𝒄𝒎𝟐)S= 336 𝒄𝒎𝟐 + 9𝟔𝒄𝒎𝟐= 432𝒄𝒎𝟐
OR
S= 2 (8)(6) + 2(6)(12)+ 2 (8)(12) S= 𝟗𝟔 + 𝟏𝟒𝟒 + 𝟏𝟗𝟐= 432𝒄𝒎𝟐
Find the Surface Area
P = 10+24+26=60
B = 𝟏
𝟐(24)(10)= 120
S = (60)(20) + 2 (120)= 1200 + 240= 1440 𝒊𝒏𝟐
