Answer:
Length=10 Inches
Width=10 Inches
Step-by-step explanation:
Volume of the box 
Height=8 Inches
Base Perimeter =40 Inches
Volume of a box=lbh
SInce h=8 in, V=800.
Then:
8bl=800
bl=100

Base Perimeter=40 Inches
Perimeter of the Base= 2(l+b)
Therefore: 2(l+b)=40
Substituting 

Recall:

Therefore:
Length=10 Inches
Width=10 Inches
Answer:
The problem is not provided so I cannot solve anything.
Step-by-step explanation:
Answer:
in terms or pi
simplified
Step-by-step explanation:
To solve this, we are using the Cylinder's volume formula:

where
is the volume of the cylinder
is the radius of the cylinder
Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius:
. Now, 9 1/2 inches is 9 and a half inches, so
.
Replacing values:




We can conclude that the volume of our cylinder is
in terms of pi, or
simplified.
Answer:
Hi! The formula for surface area is:
area = 2lw + 2lh + 2hw
(l = length, w = width, h = height.)
