    Cubics, squares.

    The problem:


    The volume of a rectangular box is 192 centimeters. What is the height of the box if the area of the base is 48 square centimeters.


    How do I solve this? Am I supposed to turn the square centimeters into cubic CMs? If so, how? (I know to find the volume of a rectangle to go V=lw) Am I even on the right track?



    Basically I have no idea what in the world I'm doing.

    Hello,

    the volume of a cuboid is calculated by:

    V = \underbrace{length \cdot width}_{\text{base area}} \cdot  height

    Plug in the values you already know into the above given equation:

    192 cm^3 = 48 cm^2 \cdot height\ \Longrightarrow \ height = \frac{192 cm^3}{48 cm^2} = 4 cm
