A hall is 15m long and 12m broad If the sum of the areas of the floor and the ceiling

given l=15m,b=12m,h=?
according to the question
2(l*b)=2(l*h)+2(b*h)
2(15*12)=2(15*h)+2(12*h)
360=30h+24h
h=6.66m
thus the volume of hall=l*b*h=15*12*6.6=1200 m^3

180*2=2*(h*12)+2*(h*15)
so h=20/3
volume=12*15*(20/3)=1200 m3

2*(15*12)=2*(h*15)+2*(h*12)
54h=360
h=6.66
volume=6.66*12*15=1198.8 m^3

as the question given as.....
given l=15m,b=12m,h=?
according to the question
2(l*b)=2(l*h)+2(b*h)
2(15*12)=2(15*h)+2(12*h)
360=30h+24h
h=6.66m
thus the volume of hall=l*b*h=15*12*6.6=180*6.6

area of floor + area of ceiling =2*(area of wall according to long)+ 2*(area of wall according to broad)
15*12 +15*12=2*(hight*15)+ 2*(hight*12)
hight=360/54
so, volume=(360/54)*15*12=1200

360=4*(12*h)
h=30/4
now- volume = l*b*h
15*12*(30/4)=1350
answer=1350

1200m^3
h=15*12/15+12=20/3
volume=15*12*20/3=1200

2(15+12)*h=15*12
h=180/27=20/3
volume is=15*12*20/3=1200cm^3

12×15×6.66=1198.8m^3

2(15x12) = 2(15xh) + 2(12xh)

solving above we get h = 20/3

volume of cuboid = lbh

20/3 x 15 x 12 = 1200
