How do I calculate the total volume for the objects below using V=l×w×h​

Find the area of an equilateral triangle with a side of 6 inches

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

The radius of the earth is two times the radius of the moon. what fraction of the volume of the earth is the volume of the moon?
