Answer:

384cm

Step-by-step explanation:

This is because if each side length is 8cm, then you would multiply 8x8 to get  64.  After that, you would multiply 64 and 6 because there are six sides on a cube and each side has an area of 64 cm.

A triangular pyramid has a volume of 333 and one-third yards cubed. What are the possible measures of the area of the base, B, a
FrozenT [24]

To find the option that satisfies the volume of the triangle, we can solve each option.

Formula for the volume a triangular prism: V = 1/3bh

Option A:

B = 50 centimeters squared; h = 10 centimeters

V = 1/3(50)(10)

V = 1/3(500)

V = 166.666... or 166 2/3 yards.

Therefore, this option is incorrect.

Option B:

B = 50 centimeters squared; h = 30 centimeters

V = 1/3(50)(30)

V = 1/3(1500)

V = 500 yards.

Therefore, this option is incorrect.

Option C:

B = 100 centimeters squared; h = 10 centimeters

V = 1/3(100)(10)

V = 1/3(1000)

V = 333.333... or 333 1/3 yards.

Therefore, this option is correct.

Option D:

B = 100 centimeters squared; h = 30 centimeters

V = 1/3(100)(30)

V = 1/3(3000)

V = 1000 yards.

Therefore, this option is incorrect.

Hence, the correct answer is [ B = 100 centimeters squared; h = 10 centimeters ]

Best of Luck!

Which of the following sets of possible side lengths forms a triangle? 6, 9, and 15 4, 10, and 15 10, 15, and 25 12, 12, and 23
Sidana [21]

Answer:  12, 12, and 23

Step-by-step explanation:

By definition, when three lengths form a triangle, the sum of two of them must be greater that the third lenght.

To find out which of the options given in the problem form a triangle, you must add the first two lenghts and verify that the sum is greater than the third lenght.

Keeping this on mind, when you verify the last option you have:

12+12=24

24>23

Therefore, the answer is the last option.
