Mr. Boccio lost the top to the storage box that holds the calculators. He wants to storage box a different color for the next school year. What is the surface area of
the storage box he is painting?
3 ft.
2 ft.
2 ft.
a) 32 ft2
b) 26 ft2
c) 7 ft2
d) 12 ft2

a. 32 ft²

Step-by-step explanation:

Given:

L = 3 ft

W = 2 ft

H = 2 ft

Required:

Surface Area of the box

SOLUTION:

Surface area = 2LW + 2LH + 2HW

Plug in the values

Surface area = 2(3*2) + 2(3*2) + 2(2*2)

SA = 12 + 12 + 8

SA = 32 ft²

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
