what is the surface area of the prism?

  =234 mm^2

Step-by-step explanation:

The surface area of a rectangular prism is given by

SA = 2 (lw +lh +hw)  where l is the length, w is the width and h is the height

SA = 2 ( 15*3 + 15*4 + 3*4)

     = 2( 45+60+12)

    = 2(117)

    =234 mm^2

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100
