Find the volume of a cube whose sides are each 4 centimeters long

V =64 cm^3

Step-by-step explanation:

The volume of a cube is given by

V =s^3

We know the side length is s=4

V =4^3

V =64 cm^3

an altitude of 15,000 feet

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
