SURFACE Area = 2B (base) + P (perimeter of base)* h (height) LATERAL Area = p*h 1. LA = 3(10*14) 3 faces of triangle LA = 420 sq in B = 1/2 8*12 B = 48 sq in SA = 420 + 2(48) SA = 516 Answer 516 sq in 2. LA = 5*14*3 LA = 210 sq ft B = 1/2 8*3 B = 12 sq ft SA = 210 + 2(12) SA = 234 Answer 234 sq ft 3. LA = 20*17*3 LA = 1020 sq yd B = 1/2 15*16 B = 120 sq yd SA = 1020 + 2(120) SA = 1260 Answer 1260 sq yd
