Answer:

A=6a²=6·82=384

Step-by-step explanation:

To find the surface area of a cube, use the formula: surface area = 6s², where s is the length of one of the sides. If you don't know the length of the sides, you can find the surface area using volume. Just find the cube root of the volume, which is equal to the length of one side of the cube.

True or False? Tell whether the pair of ratios form a proportion. 49/21 and 28/12 Please explain why you chose what you chose.

mafiozo [28]

Answer:

True, they form a proportion because their cross-multiplication products are equal.

Step-by-step explanation:

$\frac{49}{21} =\frac{28}{12}$ True or False?

If they are a proportion, the products you get from cross-multiplying are the same.

Multiply the left numerator by right denominator:

49 X 12 = 588

Multiply the left denominator by right numerator:

21 X 28 = 588

588 = 588

Therefore it is true, 49/21 and 28/12 form a proportion.
