step 1
Find out the scale factor
Remember that
If two figures are similar, then the ratio of their volumes is equal to the scale factor elevated to the cubic
so
Let
s ----> scale factor
s^3=11,000/8,019
s=1.11
step 2
Remember that
If two figures are similar, then the ratio of their surface areas is equal to the scale factor squared
so
s^2=SA/1,134
s=1.11
1.11^2=SA/1,134
SA=(1.11)^2*(1,134)
SA=1,400 yd2
The answer is 1,400 square yards
