Surface Area and volume

Rectangular Prism
Top= LxW= 10x5=50 m2
Front= LxW= 10x6=60 m2
Side= LxW= 6x5= 30 m2
TSA= 2 (T+F+S)
TSA= 2 (T+F+S)
TSA= 2 (50+60+30)
TSA= 2 (140)
= 280 m2
TSA= 2 (140)
= 280 m2
Triangular prism
LxW = 5x7= 135 cm
Bxh÷2
8x9 ÷ 2
72÷2 = 36 cm
135 + 36 +36 = 207 cm2
Cylinder
S.A = 2 (pie r 2 ) + (pie x d x h)
S.A= 2 (3.14 x 4 x 4) + (3.14 x 8 x 12)S.A = 2 x 50.24
