The surface area of a cube is 1,014^2. Find the volume of the cube.

Marta_Voda [28]

Let the length of one side of the cube be x. Then the surface area of the cube is A = 6x^2 = 1014 cubic units. We want the cube volume, so must first solve for x and then cube the result:

1014 cu. in.
x = square root of ----------------- = sqrt(169) = 13
6

The volume of this cube is thus (13 units)^3 = 4826809 cubic units.

The sides of a triangle are in the ratio 3:4:5. What is the length of each side if the perimeter of the

Brut [27]

Answer:

A. 22.5 cm, 30 cm, and 37.5 cm

Step-by-step explanation:

If three sides of a triangle are in the ratio 3:4:5, then the lengths of the sides are 3x cm, 4x cm and 5x cm.

The preimeter of the triangle is the sum of the lengths of all sides, thus

$3x+4x+5x=90\\ \\12x=90\\ \\x=\dfrac{90}{12}=\dfrac{30}{4}=7.5\ cm$

So, the lengths of the triangle's sides are

$3x=3\cdot 7.5=22.5\ cm\\ \\4x=4\cdot 7.5=30\ cm\\ \\5x=5\cdot 7.5=37.5\ cm$
