WILL MARK BRAINLIEST! What is the volume of a box with a length of 9 cm, a width of 5 cm and a height of 7 cm ?

315 cm³

Step-by-step explanation:

Volume of a box = Length × Width × Height

⇒ Substitute in the values

Volume of a box = 9 × 5 × 7

⇒ Simplify

Volume of a box = 315 cm³

Step-by-step explanation:

good luck! have a nice day!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
