Mike wants to purchase a wall unit, but he needs to determine the volume before buying it. If the wall unit is 3 feet deep, what is the volume of this wall unit?

The correct answer is 27 cubic feet.

Step-by-step explanation:

Mike wants to purchase a cubical wall unit.

But before buying the unit, Mike wants to find the volume of this wall unit.

Dimension of the wall unit is 3 feet.

Volume of a cube is given by where a is the length of the side.

Therefore volume of the cubical wall unit is = 27 cubic feet.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
