Activity 3:
Solve the problems using polynomial equation.
A carpenter wants to create a specialized medicine cabinet with a volume of 1600cmhe wants the
width to be 2 cm shorter that the length and the height to be twice the length. What should be the
dimensions of medicine cabinet?

Answer:
L = 10cm
W = 8cm
H = 20cm
Step-by-step explanation:
Given: vol=1600
Let L=length, W= width, H=height
W = L-2 ; width is 2cm shorter than length.
H = 2L; height is twice the length
V=LWH
1600=L(L-2)(2L)
1600=2L3-4L2
by trial and error we try to look for one of the roots. since the volume is 1600,. so its around close to this number.
another hint is the value should be the LCM of the constant 2 and 1600.
lets try L = 10
2000 - 400 = 1600
1600 = 1600
therefore one of the roots is 10
if L=10cm
W= L-2 = 10-2 = 8cm
H = 2W = 2(10) = 20cm
