The mass of Box A and Box B is 0.6 kg. The mass of Box A and Box C is 1.3 kg. Box C is 3 times as heavy as Box B. Find the mass of Box A.

A=0.25

B=0.35

C=1.05

Step-by-step explanation:

1. A+B=0.6

2. A+C=1.3

3. C=3B

2 subtract 1:

3 substituted:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
