Question

please answer this question as fast as possible and the correct one would be marked as brainliest+thank you+20 points AND WITH EXPLANATION PLZ find the volume of a cubical box if the cost of painting its outer surface is Rs.1440 at the rate of Rs.15 per sq. m DARE NOT TO GIVE WRONG OR BLANK ANSWERS!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

total surface cube = 1440÷15

=96

tsa of cube = 6x square

6x ^{2}

6x^2 = 96

x=4

vol of cube = x cube

{x}^{3}

hence

vol of cube = 4^3

= 64cm cube

Answer 2

Answer:

64 m³

Step-by-step explanation:

Total cost of painting the surface of a cubical box = 1440

rate = 15 per m²

Total surface = 1440/15 = 96 m²

∴ Side = √96/6

           = √16

           = 4 m

Now,

Volume = (Side)³

             = 4³

            = 64 m³

Hope it helps!
