Question

write the formula of surface area and volume of different shapes
​

Answer 1

Answer:

Cube: Surface area = 6 × a2

Right circular cylinder: Surface area = 2 × pi × r2 + 2 × pi × r × h. ...

Rectangular prism: Surface area = 2 × l × w + 2 × l × h + 2 × w × h. ...

Sphere: Surface area = 4 × pi × r2 ...

Right circular cone: Surface area = pi × r2 + pi × r ×( √(h2 + r2)) ...

Right square pyramid: Surface area = s2 + 2 × s × l.

Answer 2

Answer:

follow me plzzzzz

Step-by-step explanation:

Volumes

cube = a3

rectangular prism = a b c

irregular prism = b h

cylinder = b h = [pi] r2 h

pyramid = (1/3) b h

cone = (1/3) b h = 1/3 [pi] r2 h

sphere = (4/3) [pi] r3

ellipsoid = (4/3) pi r1 r2 r3

Surface Areas

cube = 6 a2

prism:

(lateral area) = perimeter(b) L

(total area) = perimeter(b) L + 2b

sphere = 4 [pi] r2
