If two pyramids are similar and the ratio between the lengths of their edges is 2: 7 what is the ratio of their volumes

8 : 343

Step-by-step explanation:

given that the figures are similar and the ratio of their edges is

2 : 7 then the ratio of the corresponding volumes is

2³ : 7³ ( cube of the linear ratios )

= 8 : 343

answer: its the third option.

step-by-step explanation:

i just took the test.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
