BOOK-GUIDED ORIGINAL SSC MATHS PRACTICE — Solid Mensuration

FOUNDATION

Cuboid volume = length × width × height.

METHOD

Identify the quantities given, choose the exact relationship, calculate in the same unit, then check the answer against the question.

WORKED EXAMPLE 1

A cuboid measures 18 cm × 11 cm × 12 cm. Find its volume (cm³).

Volume = length×breadth×height = 18×11×12=2376 cm³.

WORKED EXAMPLE 2

A cuboid measures 16 cm × 8 cm × 7 cm. Find its volume (cm³).

Volume = length×breadth×height = 16×8×7=896 cm³.

IMPORTANT EXCEPTION / COMMON TRAP

Volume uses cubic units, not square units.

QUICK REVISION

Cuboid volume = length × width × height.
