Answer:
A Yes
Step-by-step explanation:
the ratio is 2:1
Answer:
216 ft³
Step-by-step explanation:
h*w*l=v

Let side be "a" cm. So another side is (30-2a)/2=15-a
S=ab=a(15-a)=15a-a^2 - parabola
maximum when a = -15/-2=7.5 cm
When a=7.5 all sides are 7.5 cm
So it's a square. S=a*a=7.5*7.5=56.25 cm^2 - max
There is no global minimun for S.(look at the graphic)
Answer:
Top and bottom= 12cm2
front and back= 36cm2
left and right= 24cm2
Surface Area = 72 cm2
Step-by-step explanation:
Top and bottom= 2×(3×2)12cm2
Surface Area = 2×(3×2 + 3×6 + 2×6) = 72 cm2
