Answer:
64
Explanation:
The volume of a prism is defined by the product of its length (L) times its width (W) times its Height (H):
![Volume= L * W * H](https://img.qammunity.org/2020/formulas/mathematics/middle-school/md5k2699aiizigjka318dt7l1wwqqdli9r.png)
So, if these dimensions are increased each by a factor of 4, the volume now becomes:
![Volume= 4L *4 W * 4 H = 64 L*W*H](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9w28oz7kj82opgl5jxmw35zx84qhausiqo.png)
That is 64 times the original volume LWH
