Volume/Surface Area

Question 1

Lateral Area (LA)

Answer 1

Sum of the area of all sides except the base(s)

Question 2

Surface Area (SA)

Answer 2

Sum of the area of all sides (LA + B)

Question 3

Cylinder LA

Answer 3

LA = 2πrh

Question 4

Cylinder SA

Answer 4

SA = 2πrh + 2πr²

Question 5

Cone LA

Answer 5

LA = πrl

Question 6

Cone SA

Answer 6

SA = πrl + πr²

Question 7

Sphere SA

Answer 7

SA = 4πr²

Question 8

centroid

Answer 8

intersection of the medians located 2/3 of the distance from a vertex along a median

Question 9

area of equilateral triangle

Answer 9

s2(sqrt(3))/4

Question 10

Tetrahedron SA

Answer 10

SA = s²√3

Question 11

Rectangular Prism SA

Answer 11

SA = 2(lw + lh + wh)

Question 12

Rectangular Prism Volume

Answer 12

V = lwh

OR

V = Bh

Question 13

Cube SA

Answer 13

SA = 6s²

Question 14

Cube Volume

Answer 14

V = s³

OR

V = Bh

Question 15

Pyramid SA

Answer 15

SA = B + xA_triangle

(x-the coefficient, depends on the number of triangles in the pyramid, which depends on the shape of the base)

Question 16

Pyramid Volume

Answer 16

1/3(Bh)

Question 17

Tetrahedron Volume

Answer 17

V = (s³√2)/12

OR

V = 1/3(Bh)

Question 18

Cylinder Volume

Answer 18

V = πr²h

OR

V = Bh

Question 19

Cone Volume

Answer 19

V = 1/3(πr²h)

OR

V = 1/3(Bh)

Question 20

Sphere Volume

Answer 20

V = 4/3(πr³)
