You are building a 3-foot tall dresser. You want the volume to be 42 cubic feet.a. What should the area of the base be?b. Give a posible length & width of the base.c. Make a hand drawn sketch of the dresser with the dimensions you chose.

Respuesta :

The volume of the dresser can be calculated through the formula:

[tex]V=A_b\ast h[/tex]

where Ab is the area of the base and h the height of the building, then, clear the equation for the area of the base,

[tex]A_b=\frac{V}{h}[/tex]

Now replace with the given values,

[tex]\begin{gathered} A_b=\frac{42ft^3}{3ft} \\ A_b=14ft^2 \end{gathered}[/tex]

Then, suppose the base is a rectangle, then the area's formula is:

[tex]A_b=l\ast w[/tex]

give the length a value of 2 ft, and clear the formula for the missing measurement

[tex]\begin{gathered} 14ft^2=2ft\ast w \\ w=\frac{14ft^2}{2ft} \\ w=7ft \end{gathered}[/tex]

Answer:

a. 14 ft²

b. length=2ft; width=7ft

c.
