Decompose the prism into two rectangular prism.

Prism 1 will have the following dimensions and volume:

Length = 10 cm

Height = 8 cm

Width = 9 - 5 = 4 cm

Volume = L × W × H

Volume = 10 × 8 × 4 = 320 cm³

Prism 2:

Length = 10 cm

Height = 3 cm

Width = 5 cm

Volume = 10 × 3 × 5 = 150 cm³

✔️Volume of the entire prism = 320 + 150 = 470 cm³

Genrish500 [490]

Answer:

The number of Girls players in the Team of 18 players is 6 .

Step-by-step explanation:

Given as :

The total number of player including boys and girls = 18

And \frac{1}{2} times girls player +  \frac{1}{3} times boys player = 7

Let The number of boys player = B

The number of girls player = G

So, According to question

G + B = 18      ...1

\frac{1}{2} × G +  \frac{1}{3} × B= 7

or, \frac{G}{2}  +  \frac{B}{3} = 7    ...2

or, Put the value of B from  eq 1

or,  \frac{G}{2}  +  \frac{18 - G}{3} = 7  

Or,  \frac{G}{2}  -  \frac{G}{3}  + 6 = 7

or,  \frac{3G - 2G}{6}  = 7 - 6

Or,  \frac{G}{6}   = 1

∴ G = 1 × 6 = 6

Hence The number of Girls players in the Team of 18 players is 6 . Answer
