How many unit cubes are required to create a larger cube with edge length 3 units?
kiruha [24]

Answer:

The unit cubes that are required to create a larger cube with an edge length of 3 units is:

27 cubes.

Step-by-step explanation:

To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:

To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:

If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.

Candace has $15 more than Amar. Their combined my money totals $85. Which system of equations represents this equation?
LenaWriter [7]

Answer: See explanation

Step-by-step explanation:

Let Amara money be represented by a

Since Candace has $15 more than Amar. Therefore, Candace money will be = a + 15

Their total money will be 85 and this can be represented in an equation as:

a + (a + 15) = 85.

a + a + 15 = 85

2a + 15 = 85

2a = 85 - 15

2a = 70

a = 35

Amar money = $35

Candace money = $35 + $15 = $50
