If the area of the base of a cube is 100m, whats the volume
Licemer1 [7]

Answer:

1000 m³

Step-by-step explanation:

The base of a cube is just a square.

The area of a square is l^2, where l is the length.

Since we know the area of the base (the square) we can find l easily.

l^2 = 100\\\\l = \sqrt{100}\\\\l=10

Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.

This means the height of the cube is also 10m.

Since the volume of a cube is represented as l^3, where l is the length, we can substitute 10 in as l to find it's total volume.

10^3 = 1000

So the volume of this cube is 1000 m³.

Hope this helped!

(8/a+4)+(10/b-6)

so common denominator is (a+4)(b-6)

=(8/a+4) *(b-6/b-6)+(10/b-6)*(a+4/a+4)

= 8(b-6) / (a+4)(b-6) + 10(a+4)/(a+4)(b-6)
