The most basic approach here is to simplify as much as possible. Therefore you do:
(1/2 x 8x + 1/2 x 4) - (1/3 x 3x + 1/3 x 9) =17
(4x + 2) - (x + 3) = 17
4x + 2 - x - 3 = 17
3x - 1 = 17
Then you pass the one on the other side which gives:
3x = 17 + 1
3x = 18
Finally divide everything by 3:
x = 6
The answer to the question is... 12
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
