We know a cube has 6 equivalent sides. One side has an edge of 2 ft so the other edges are all 2 ft so 6(2 x 2) or 2 x 2 + 2 x 2 + 2 x 2 + 2 x 2 + 2 x 2 + 2 x 2 = 24ft.

$3840 {ft}^{3}$

EXPLANATION

The room represents a rectangular prism or a cuboid.

The dimensions of the room are 30 feet by 16 feet by 8 feet(height).

The volume of a rectangular prism is

$= base \: area \: \times \: height$

Substitute the given values

$= 30 \times 16 \times 8 {ft}^{3}$

Simplify:

Answer:

K = -72

Step-by-step explanation:

1. Get K/9 by itself to do so add 3 to both sides eliminating it on the left by turning the -11 into -8

2. Multiply by 9 on both sides eliminating the division of 9 on the left and turning -8 into -72 leaving the equation as K = -72

To eliminate a number you must do its opposite so the opposite of -3 is +3 so you +3 to both sides. And always start the equation by eliminating what is not connected to the variable in this case the 9 was connected to the variable as K/9.
