Question

Each side of a cube is measured to be 7.203 m. The total surface area and the volume of the cube to appropriate significant figures are (A) 311 m 2, 374 m 3 (B) 311.3 m 2, 373.7 m 3 (C) 311.3 m 2, 373.72 m 3 (D) 311.299 m 2, 373.715 m 3

In multiplication or division, the final result should retain as many significant figures as are there in the original number with the least significant figures. Here the length has 4 significant figures, hence so would the surface area and volume.

Q. Each side of a cube is measured to be $7.203 m$ . The total surface area and the volume of the cube to appropriate significant figures are

$311 m^{2}, 374 m^{3}$

$311.3 m^{2}, 373.7 m^{3}$

$311.3 m^{2}, 373.72 m^{3}$

$311.299 m^{2}, 373.715 m^{3}$

In multiplication or division, the final result should retain as many significant figures as are there in the original number with the least significant figures. Here the length has $4$ significant figures, hence so would the surface area and volume.
