Worksheet 5: Answer Key (difficulty - easy)
Fill in the blanks and show all your work.
Cube
Name of the solid: _______________________________
5 cm
L.A. + 2 B
Equation for formula: S.A. = _____________________________
B h
Equation for formula: V = ________________________________
square
First, I will solve for the area of the Base, which is a ____________________________.
Describe your process through a series of clearly shown mathematical steps.
B = S 2
B = 5 2
B = 25
25 cm 2 square
B = ____________________
Next, I will solve for the Lateral Area, which is a _____________________________.
Describe your process through a series of clearly shown mathematical steps.
First I will find the
Now I can find the
perimeter of the base, P.
lateral area, L.A.
P = 4 S
L.A. = P h
P = 4 (5) L.A. = 20 (5)
P = 20 L.A. = 100
100 cm 2 L.A. + 2 B B h
L.A. = ____________________
Write the equations. S.A. = __________________________ V = __________________________
Replace variables with
their value. S.A. = __________________________ V = __________________________
Solve the equations.
100 + 2 (25) 25 (5)
S.A. = 100 + 50
150 cm 2 125 cm 3
(Show all algebraic steps.) S.A. = __________________________ V = __________________________
