Sompong's Surface Area and Volume Post

Volume

v= (aofb)xh
v= (bxh/2)xh
v= (3x5/2)x8.5
v= 7.5x8.5
v= 63.75m³ = 63.8m³

v= (aofb)xh
v= (lxw)xh
v= (20x8)x16
v= 160x16
v= 2560cm³

^{v= (aofb)xh
v= (bxh/2)xh
v= (8x4/2)x6.5
v= 16x6.5
v= 104cm³
104/8= 13cm^{3
13x3= 39cm³}}

r= d/2
r= 12/2
r= 6cm

v= (aofb)xh
v= (3.14x6² )x15
v= 113.04x15
v= 1695.6cm³
