Answer 2

Answer:

750 m³

Step-by-step explanation:

Height of step = 1/4 m

Height of next step will be 1/4 + 1/4 m = 1/2 m

Then next height = 1/4 + 1/2

                            = ( 2 + 1 )/4 = 3/4

Volume = length × breadth × height .

breadth × length = 50 × 1/2 = 25 m² for all  .

Total volume :

25 × 1/2 + 25 × 1/4 + ............... 15/4

Take 25 as common :

= > 25 ( 1/4+ 1/2+ ............ 15/4 )

This can be written as :

= > 25 ( 1/4 + 2/4 + 3/4 + ........ 15/4 )

= > 25 ( 1 + 2 + 3 .... 15 ) / 4

= > 25/4 ( 1 + 15 ) 15/2

= > 25/4 × 16 × 15/2

= > 25 × 4 × 15/2

= > 25 × 2 × 15

= > 50 × 15

= > 750

The volume is 750 m³ .
