Work: Calculate the value of equation 1/2*1620*454^2-1/2*(1620-180)*(454-120)^2 .
Question type: Mathematical calculation
Solution:
1/2*1620*454^2-1/2*(1620-180)*(454-120)^2
=1/2*1620*454^2-1/2*1440*(454-120)^2
=1/2*1620*454^2-1/2*1440*334^2
=1/2*1620*206116-1/2*1440*334^2
=1/2*1620*206116-1/2*1440*111556
=0.5*1620*206116-1/2*1440*111556
=810*206116-1/2*1440*111556
=166953960-1/2*1440*111556
=166953960-0.5*1440*111556
=166953960-720*111556
=166953960-80320320
=86633640
Answer:1/2*1620*454^2-1/2*(1620-180)*(454-120)^2=86633640
