A giant box has the dimensions of 1.5m x 0.75m x 0.6m. It stores smaller boxes with
dimensions of 5cm x 3cm x 4cm. If each
smaller box weighs 500g, and the big box
weighs 6000 kg when it is full, how much does
it weigh when it is empty?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
