Given:
Side length of base = 8
Slant height = 6
To find:
The surface area of the square pyramid.
Solution:
Surface area:
where A is the area of base
p is the perimeter of base
s is the slant height
Area of base (A) = 8 × 8
= 64
Perimeter of base(P) = 4 × 8
= 32
Substitute these in the formula:
The surface area of the square pyramid is 160 unit².
Answer:
0.21 square meter
Step-by-step explanation:
Area of the section of wall = 1 square meter
Dimension of part of mural completed = meter by
meter
Part of the mural completed = Area of the rectangular part of mural completed
But,
Area of a rectangle = length x width
So that,
Part of the mural completed = length x width
= x
=
= 0.2083
Part of the mural completed = 0.21 square meter
The part of the mural that has been completed by Beverly is 0.21 square meter.
