Given the statement:
A piece of wood has a width of 5 cm and a height of 10 cm. Its volume is 100 cm^3.
Determine the length of the wood.
Formula for the volume:
V = l x w x h
Solution:
Substitute the given values of V, w, and h to the formula for the volume of the wood and then solve for l.
V = l x w x h
100 cm^3 = (5cm)(10cm) (l)
100 cm^3 = 50 cm^2 (l)
Divide both sides by 50 cm^2 in order to determine the value of l.
100 cm^3/50 cm^2 = 50 cm^2 l /50 cm^2
l = 2 cm
Finala answer:
The length of the wood is 2cm.
