Question

A cuboid has sides of 10.4 cm, 3.8 cm and 1.02 cm. Choose the correct statement(s) about the area of the faces and its volume with due regard to significant digits.

G1 Physics · Accepted Answer

Largest face = 10.4×3.8 = 39.52 cm² but must be reported with 2 significant figures, so A is false. Smallest face = 3.8×1.02 = 3.876 ≈3.9 cm², so B is true. Volume = 10.4×3.8×1.02 = 40.3104 ≈4.0×10¹ cm³, so C is true. Correct answers: B,C.
