320,000 / 3,840 = 730,000 / x
cross multiply because this is a proportion
(320,000)(x) = (3,840)(730,000)
320,000x = 2,803,200,000
x = 2,803,200,000 / 320,000
x = 8760 <====

Answer:
B. 192.5 ft³
Step-by-step explanation:
To find the volume of a triangle prism, multiply the base, height, and length together, and then divide it by 2 (or multiply that by 0.5).
(5 * 7 * 11)/2
Multiply 5 by 7 to get 35.
(35 * 11)/2
Multiply 35 by 11 to get 385.
385/2
192.5 ft³ is the volume of this triangluar prism.
