Work: Calculate the value of equation 0.6×1.5×11+0.9×1.5×28+1.2×1.5×402+1.5×1.5×20 .
Question type: Mathematical calculation
Solution:
0.6×1.5×11+0.9×1.5×28+1.2×1.5×402+1.5×1.5×20
=0.9×11+0.9×1.5×28+1.2×1.5×402+1.5×1.5×20
=9.9+0.9×1.5×28+1.2×1.5×402+1.5×1.5×20
=9.9+1.35×28+1.2×1.5×402+1.5×1.5×20
=9.9+37.8+1.2×1.5×402+1.5×1.5×20
=9.9+37.8+1.8×402+1.5×1.5×20
=9.9+37.8+723.6+1.5×1.5×20
=9.9+37.8+723.6+2.25×20
=9.9+37.8+723.6+45
=47.7+723.6+45
=771.3+45
=816.3
Answer:0.6×1.5×11+0.9×1.5×28+1.2×1.5×402+1.5×1.5×20=816.3
