Prismoidal formula for this quest. is (d/6)*{A1 + A2 + 4*Am}.
A1= 24m2,
A2= 8 m2,
Am= (24+8)/2= 16m2,
Vol.= (6/6)*{ 24+8+(4*16)},
= 96m3.
A1= 24m2,
A2= 8 m2,
Am= (24+8)/2= 16m2,
Vol.= (6/6)*{ 24+8+(4*16)},
= 96m3.

Prismoidal Formula= L/6(A1+A2+4Am),
A1- 6x4 =24m2.
A2- 4x2 =8m2.
Am= mean width - (6+4)/2=5m x mean depth (4+2)/2=3m, So Am = 15m2.
Vol = 6/6(24+8+4*15) = 92 m3.
A1- 6x4 =24m2.
A2- 4x2 =8m2.
Am= mean width - (6+4)/2=5m x mean depth (4+2)/2=3m, So Am = 15m2.
Vol = 6/6(24+8+4*15) = 92 m3.
