Question

the length of the bos is 2 1/2m, it is 1 9/16 times its width. What is the height of the box if its volume is 12 3/4m^3

Answer 1

Answer:

h=1.3056 m

Step-by-step explanation:

L=2.5m

w=L(1 + 9/16)

w=2.5(1 + 9/16)=$\frac{125}{32}$ m=3 $\frac{29}{32}$m

v=Lwh

12.75m³=(2.5m)($\frac{125}{32}$m)h

12.75m³=(9.765625m²)h

$\frac{12.75m^{3} }{9.765625m^{2} }$=h

h=1.3056 m

Answer 2

Answer:

3 3/16

Step-by-step explanation:

If:

Length= 2 1/2

Width=2 1/2 divided by 1 9/16= 1 3/5

Volume=12 3/4

So then, 2 1/2 times 1 3/5=4

12 3/4 divided by 4= 3 3/16

Done!
