The length of a cuboid is thrice its width. The height and volume of the cuboid measure 4cm and 300 cubic cm, respectively. What is the length of this cuboid?

Correct answer:

l =  15 cm
w =  5 cm

Step-by-step explanation:

l=3w h=4 cm V=300 cm3  V = lwh V = 3wwh = 3w2h  w=3 hV=3 4300=5 cm  l=3 w=3 5=15 cm
w=5=5 cm   Verifying Solution:   V2=l w h=15 5 4=300 cm3
