A cube has a surface area of 486cm^2. what is its side length?

9 cm

Step-by-step explanation:

Total surface area of a cube =486 cm²

 We know that the surface area of the cube

=6l²

 Therefore,

6l ² =486

l² =81

l =9 cm

33

step-by-step explanation: g=6

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
