Answer:

It is given that the side of the cube is 7.203m.

Total surface area of cube,

S = 6(area of one face) = 6l2 = 6 (7.203)2

S = (311.29925) m2

S = 311.3 m2 (after rounding off)

Volume of the cube, V = l3 = (7.203)3 = 373.714754427 m3

V = 373.7 m3 (rounded off)

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) = 6l2 = 6 (7.203)2

S = (311.29925) m2

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

S = 311.3 m2

Volume of the cube, V = l3 = (7.203)3 = 373.714754427 m3

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

V = 373.7 m3
