Which expression can be added to find the volume of the solid figure? Select all that aplly.

D.4*6*1 and6*4*3

we have :

volume of solid=volume of upper cuboid

+volume of lower

=l*b*h+l*b*h=6*4*3+6*4*1=96m³

now

A.

4*3*7+1*3*4=96[neglected]

B.

4*6*7+1*3*3=177 [neglected]

C.

1*4*7+4*3*6=100[neglected]

D.

4*6*1+6*4*3=96[Verified]

E.

4*6*3+7*3*3=135[neglected]

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
