Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
Answer:
Multiplier: -175/3
Decrease: 23⅓ %
Step-by-step explanation:
75 = 250 - 3(d)
d = -175/3
Y = 250 - (175/3)m
Where m is the no. of months
Y is the new value
(175/3)/250 × 100 = 70/3 %
Or 23⅓ %
