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.
Answer:
218
Step-by-step explanation:
this is ratio.
5+4=9. which is the ratio you add it.
5/9×360=200
therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.
therefore the number of boys in school from january to february is 218.
