Volume/Surface Area Flashcards
1
Q
Lateral Area (LA)
A
Sum of the area of all sides except the base(s)
2
Q
Surface Area (SA)
A
Sum of the area of all sides (LA + B)
3
Q
Cylinder LA
A
LA = 2πrh
4
Q
Cylinder SA
A
SA = 2πrh + 2πr2
5
Q
Cone LA
A
LA = πrl
6
Q
Cone SA
A
SA = πrl + πr2
7
Q
Sphere SA
A
SA = 4πr2
8
Q
centroid
A
intersection of the medians located 2/3 of the distance from a vertex along a median
9
Q
area of equilateral triangle
A
s2(sqrt(3))/4
10
Q
Tetrahedron SA
A
SA = s2√3
11
Q
Rectangular Prism SA
A
SA = 2(lw + lh + wh)
12
Q
Rectangular Prism Volume
A
V = lwh
OR
V = Bh
13
Q
Cube SA
A
SA = 6s2
14
Q
Cube Volume
A
V = s3
OR
V = Bh
15
Q
Pyramid SA
A
SA = B + xAtriangle
(x-the coefficient, depends on the number of triangles in the pyramid, which depends on the shape of the base)
