Answer:
914 m^2 to the nearest whole number.
Step-by-step explanation:
The area of the hexagonal base is made up of 6 congruent triangles so its area = 6 * 1/2 base * height
= 6 * 1/2 * 12 * 6√3
= 216√3 m^2.
The area of each slanting triangle = 6 * 15 m^2 so the lateral area of the pyramid
= 6*6*15 = 540 m^2
Total surface area = 540 + 216√3
= 914.12 m^2.

Answer:
$828
Step-by-step explanation:
15% = 0.15
0.15 x 720 = 108
total cost = $720 + $108 = $828
To solve for the width simply multiply the two numbers:
width of sidewalk = 12 * (3 7/8)
Where 3 7/8 = 31/8
so calculating,
width of sidewalk = 12 * (31 / 8)
