Aglass vase weighs 0.61 lb. how much does a similarly shaped vase made of the same glass weigh if each dimension is 2 times as large? explain. a. 2.44 lb; the vase dimensions are 2 times as large, so the weight is 4 times as much because 2sq = 4. b. 1.22 lb; the vase dimensions are 2 times as large, so double the weight. c. 9.76 lb; the vase dimensions are 2 times as large, so the weight is 16 times as much because 2sq4 = 16. d. 4.88 lb; the vase dimensions are 2 times as large, so the weight is 8 times as much because 2sq3 = 8.

Let 
x> volume of the small glass vase
D> density of the glass vase

we know that
[volume of larger glass vase]=[scale factor]³*[volume of smaller glass vase]
scale factor=2
[volume of larger glass vase]=[2]³*[x]> 8x units³

Density=mass / volume> mass =Density*Volume

the weight of the smaller glass vase=D*V> 0.61=D*x

the weight of the larger glass vase=D*8x> 8*[D*x]
therefore
the weight of the larger glass vase=8*[weight of the smaller glass vase]
the weight of the larger glass vase=8*[0.61]> 4.88 lb

the answer is the option
D. 
4.88 lb; the vase dimensions are 2 times as large, so the weight is 8 times as much because 2sq3 = 8
