Answer:
Step-by-step explanation:
PART A
A cube has 6 sides, then
One side are is: 4in x 4 in, then
As1 = 16 in2
then
Surface area = 6*(16)
Acube = 96 in^2
PART B
Area of a cylinder = 2(Pi*r^2) + 2(Pi)(r)*5
Acylinder = 2(3.14)(0.5^2) + 2(3.14)(0.5)*5
Ac = 1.57 + 15.7
Acylinder = 17,27 in2
PART C
The new height of the cylinder will be: 5-4 = 1 in
Now
Acylinder = 2(3.14)(0.5^2) + 2(3.14)(0.5)*1
Acylinder = 1.57 + 3.14
Acylinder = 4.71 in2
Best regards
