Notes / Explanation
Rectangular Box (Closed)
( V = x × y × z )
A = 2(xy + xz + yz)
6 faces (top, bottom, front, back, left, right)
Rectangular Box — Open from Top
( V = x × y × z )
( A = xy + 2xz + 2yz )
✅ Top face removed → bottom + 4 sides
Cylinder (Closed — Top & Bottom)
( V = π r

h )
( A = 2(π r

) + 2π r h )
→ ( A = 2π r(h + r) )
✅ 2 Bases (top & bottom) + Curved Surface
