Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
Answer:
the simplified expression is 32/ 81
Two figure in front
h=16+17 = 33 m
l=18 m
width = 13 m
Volume = lwh = 18*13*33 =7722 m^2
Two figures at the back
h=16 m
l=18+18 =36 m
width = 15 m
Volume = lwh =36*15*16 =8640 m^2
Total volume = 7722+8640 = 16362 m^2
