Step-by-step explanation:
We will do this.
11x - 12 = 7x
11x - 4x = 7x
4x = 12
4x/4 = 12/4
x = 3
3 x 7 = 21

Answer:
216 m³
Step-by-step explanation:
The ratio of linear dimensions is the square root of the ratio of area dimensions.
s = √(216/1014) = √(36/169) = 6/13
Then the ratio of volume dimensions is the cube of that. The smaller volume is ...
v = (6/13)³·2197 m³ = 216/2197·2197 m³ = 216 m³
The volume of the smaller solid is 216 m³.
