As long as we're talking about a rectangular prism or something of the sort, the volume would be 120 cubic inches (the product of the three numbers and then inches cubed because it's inches times inches times inches). Now if you're talking about a triangular prism, the volume would be 60 cubic inches because the formula for the area of a triangle is 1/2 base times height.
3,240 cubic units.
3240
It is: (15+18)+12 = 45
GCF(12, 15, 18) = 3
LCM of 12 and 15 and 18 is 180.
If that's a rectangular prism then it is: 18*15*12 = 3240 cubic m
-12 + 18 - (-15) = -12 + 18 +15 = 21
It is 180
(12+15+18)/3 = 15
(12+15+18)/3 = 15
6
15
15% of 120 is equal to 12% of 150. 15% of 120 = 18 12% of 150 = 18
