3375
15 cm
It is: 15 cm
If that is the side length, just multiply 15 cm x 15 cm x 15 cm.
Volume = edge3 = (15 x 15 x 15) = 3,375 cm3
V = s3 = (15 cm)3 = 3,375 cm3
A 7-cm cube has a volume of 343 cm3
The volume of the cube is: 125 cubic cm
The volume is 8 cubic cm.
With 10 cm side lengths, this cube has a volume of 1000 cm3
A cube with a side length of 4 cm has a volume of 64 cubic cm.
A cube with a side length of 11 cm has a volume of 1331 cubic cm.
NO ! You cubed the 'cm' part OK. Why did you not also cube the '15' part ? Look at this: You have a cube, 15 cm on each side. What is its volume ? Length = 15 cm Width = 15 cm Height = 15 cm Volume = (Length) x (width) x (height) (15 cm) x (15 cm) x (15 cm) = 3,375 cm3 An even slightly better way to look at it: (15 cm)3 = (15)3 x (cm)3 = (3,375) (cm3)
