Question

Each side of a cube is measure to be 7.203 m .what is the TSA and volume of cube in appropriate significant figures?​

Answer 1

Explanation:

You can see that 7.203 is three significant figures after decimals.

So,

TSA = 6l^2

= 6×(7.203)^2

= 6×51.883209

=6×51.883

= 311.928 unit^2

Volume = l^3

= (7.203)^3

= 313.714754

=313.715 unit^3

Answer 2

Answer:

here ,

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)
