Question

Harry has a cube with a side length of 7cm. What is the volume of Harry’s cube?

Answer 1

343cm^3

as 7x7x7 = 343

Answer 2

Answer:

$\huge\boxed{343 \ cm^3}$

Step-by-step explanation:

We know that the side length of a cube is 7 cm.

The formula to find the volume of a cube is $l^3$, where l is the length of the cube.

So we can substitute our length in (7) into the formula.

$7^3$

Now, what does it mean to cube something? To cube something is to multiply it by itself 3 times.

If we had the number n cubed, it would be

$n \cdot n \cdot n$

So we can do the same if we cube 7.

$7 \cdot 7 \cdot 7 = 49 \cdot 7 = 343$

Hope this helped!
