Answer:

[you need 343 1 inch cubes]

Step-by-step explanation:

A foot has 12 inches. So if the edge length is 7/12 of a foot, that means that the edge length is 7 inches.

——————

[volume of a cube if the edge length is L, is L x L x L or L cubed]

A one inch cube has an edge length of 1. That means the volume of this cube is 1 x 1 x 1 = 1 inch cubed

——————

This big cube, has an edge length of 7 inches. So the volume is 7 x 7 x 7 = 343 inches cubed.

To find how many 1 inch cubes do you need to fill a 7 inch cube, you divide 343 by 1:

343/1=343 so you need 343 1 inch cubes.

What does a vector do to a translation

Alona [7]

Answer:

A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. In other words, a translation vector can be thought of as a slide with no rotating. The slide won’t change the shape or size of the figure, and with no rotation, the orientation won’t change either.
