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 .
Answer:
1/8 is the bigger fraction
Step-by-step explanation:
When comparing fractions with different denominators, and the numerator is one, like 1/8. The one with the smaller number for the denominator is greater.
You could also compare them by finding common denominators, so for 1/8 and 1/9, a common denominator would be /63. So you would take and multiply that by
. You would then get
. When you take
times
you get
. So when comparing you can see that 1/8 is greater than 1/9.
