Answer:
The perimeter is 22.
Step-by-step explanation:
The perimeter formula (it sometimes varies) is 2(b+h)
b being base (in this example, 6)
h being height (in this example, 5)
So now, with substitution, we are left with:
2(6+5)
Which simplifies down to:
2(11)
22
A rectangular prism is just a shape that looks like a brick.
If you think about a brick for a few seconds, you'll realize
that it has
-- 2 faces of (length by width)
-- 2 faces of (length by height)
and
-- 2 faces of (width by height).
The dimensions of the brick in question 6 are 8ft, 3ft, and 5ft.
So it has
-- 2 faces of 8ft by 3ft
-- 2 faces of 8ft by 5ft
and
-- 2 faces of 3ft by 5ft .
Can you take over and complete it now ?
Answer:
50
Step-by-step explanation:
The perimeter of a Triangle is the sum of it's 3 sides.
We are given two sides here which is side length 5.6 and a side of length 19.7
Let's us represent the third side as x
Therefore
x + 19.7 + 5.6 = Perimeter of the triangle
We would have this equation
But it is important to know that every side of a triangle must be less than the sum of the other two sides, hence
x < 19.7 + 5.6
x < 25.3
Adding 25.3 to both sides to make the left side equal to the perimeter
perimeter = x+25.3 < 25.3 + 25.3 = 50.6
Therefore, 50.6 is the smallest whole number that is larger than the perimeter of the triangle in the question above.
Therefore, the biggest whole number smaller than the perimeter of the above triangle is 50
Question 23
Lateral Surface Area = πD x height
Lateral Surface Area = π (4) (6) = 75.40 in²
Question 24
Total Surface Area = 2(8.2 x 3.4) + 2(8.2 x 2) + 2(3.4 x 2)
Total Surface Area = 36.56 in²
Question 25
Total Surface Area = 2(10 x 12) + 2(12 x 4) + 2(10 x 4)
Total Surface Area = 416 in²
