Answer:

Step-by-step explanation:
Given that,
...(1)
We need to find the value of x.
We know that,
sin30 = 1/2
Use it in equation (1).

So, the value of x is equal to
.
L = 10 mw = 11 mh = 5 md = 15.6844 mS = 430 m²V = 550 m³ x 2 = 1100m³
Agenda:l = lengthw = widthh = heightd = diagonalS = surface area V = volume
