Answer:

Option a. 0.55 m ^3

Explanation:

we know that

If two figures are similar, then the ratio of its volume is equal to the scale factor elevated to the cubic

Let

z ----> the scale factor

x ----> the volume of the model of a grain silo in cubic meters

y ---> the volume of the actual silo in cubic meters

so


z^(3) =(x)/(y)

we have


z=(1)/(10)


y=550\ m^3

substitute the values


((1)/(10))^(3) =(x)/(550)

Solve for x


((1)/(1,000)) =(x)/(550)


x=((1)/(1,000))550


x=0.55\ m^3
