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 (50+60+30)
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
100.48 + 301.44 = 401.92 mm2

V= 3.14 x 6 x 6 x 15
V= 1695.6
