Answer:
125.6 cubed inches
Step-by-step explanation:
1. 3.14(2)^2(10) - Multiply 3.14 with 2 squared and 10.
2. First find out what is 2 squared, which is 4. Then, multiply 4 with 3.14, which is 12.56.
3. Now, multiply 12.56 with 10 or just move the decimal point one place to the right, which gives you 125.6 cubed inches.
Proof method:
1. Calculate the length of each side, DE,DF,EF
2. Compare the length of them, if any pair of them is equal, then it's isosceles.
