Surface Area of Right Prisms (HSC SSCE Mathematics Standard): Flashcards

Total area of all outer surfaces of a 3D shape

Flat 2D pattern showing all surfaces of a solid spread out

Shows all faces at once, prevents missing surfaces

Sum the areas of all faces

6 faces (3 pairs of identical faces)

$SA = 2lb + 2bh + 2lh$

5 faces: 2 triangular + 3 rectangular

A = rac{1}{2}bh

A = rac{1}{2}(a + b)h

Square units (cm², mm², m²)
