Answer:
16
Step-by-step explanation:
Adam is building birdhouses that requires i.e 0.5 feet long boards.
Now, he has an i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.
We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.
Now,
So, there can be 16 whole board of exact length 0.5 feet. (Answer)
Answer:
<h3>There areStep-by-step explanation:
We know that the survey has 8 items, that means we can use the factorial number, because it's a simple permutation.
Using a factorial we have
where
, which is the total number of items.
Therefore, there are 40,320 ways to answer the survey, or 8! ways.
Answer:
The surface area of the given pyramid is 112 .
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base =
=
= 16
Area of its base = 16
Area of one of its triangular surface = x base x height
= x 4 x 12
= 2 x 12
= 24
Area of all its four triangular surfaces = 4 x 24
= 96
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112
The surface area of the given pyramid is 112 .
