Answer:
54 square feet
Step-by-step explanation:
We need to find the area of the surface touching the floor and deduct it from the total surface area of the block.
The surface area of the entire block is given as:
A = 2(lw + lh + wh)
where l = length
w = width
h = height
The dimensions of the block are 2 feet by 3 feet by 6 feet. This means that:
l = 2 feet, h = 3 feet, w = 6 feet
Therefore, the total surface area is:
A = 2[(2 * 3) + (2 * 6) + (3 * 6)]
A = 2(6 + 12 + 18)
A = 2(36)
A = 72 square feet
The area of the surface that does not need covering is:
A = 3 * 6 = 18 square feet
The surface area of the part of the block that needs covering is therefore:
A = 72 - 18 = 54 square feet
Answer:
a + b + c + d + e = 180.
Step-by-step explanation:
We can prove that a = angle CBA (vertically opposite angles are equal).
Now, since lines DE and CA are parallel, then it follows that c = angle ACE (alternate angles are equal). Similarly, b = angle CAD.
But notice that what we've just done is found the angles of the triangle CBA.
So the sum of the angles (a + b + c + d + e) is the sum of the angles of a triangle.
We then conclude that a + b + c + d + e = 180 degrees.
