Question from Heaven, a student:

Allie used 11.7m^3 of cement to make a square patio. If the thickness of the patio is 15 cm,what is the length of the patio?


Suppose the length of the patio is $L$ m then the volume of the patio slab is the area of the base times the thickness. Since 15 cm is 0.15 m the volume of the slab is

\[L \times L \times 0.15 = 11.7 m^{3}.\]

Solve for $L.$
