Question

150) 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) 311.3 m2, 373.7 m3
B) 311.29 m2, 373.7 m3
C) 311.29 m2, 373.71 m3
D) 311.299 m2, 373.714 m3​

Answer 1

Answer:

Hey mate ......

Here's ur answer :

»» It is given that the side of the cube is 7.203m. Therefore, number of significant figures in length is 4.

Total surface area of cube,

S = 6(area of one face) = 6l^2 = 6(7.203)^2

.°. S = (311.29925) m²

By rounding off it to 4 significant figures, we get,

»» S = 311.3 m^2 ,,

Volume of the cube, V = l^3 = (7.203)^3

V = 373.7147 m^3

By rounding off it to 4 significant figures, we get,

»» V = 373.7 m^3 ,,

Hence, the correct answer is option (A) 311.3 m^2 , 373.7 m^3
