Question

What is the surface area of this three-dimensional, symmetrical, capital letter “I” block? Show your work.
A solid composite figure in the shape of a capital “I” is shown. The length of the entire letter is 5 centimeters. The width is 2 centimeters. The height of the cross pieces at the top and the bottom is 2 centimeters. The length of the middle of the I is 2 centimeters long. Each distance from the outside edge of the middle piece to the outside edge of the top and bottom cross pieces is 2 centimeters.

Answer 1

There are 10 squares of 2 by 2 dimensions, area is 4x10 = 40
surface of the the 2 capital i, ((5 x 2 x 2) + (2 x 1) )x2 =44
and the top and bottom (5x2)x2 =20
the answer should be 104

Answer 2

How can this three-dimensional, symmetrical, capital letter "I" block be broken into pieces so that it results in the smallest number of parts? Describe each part with measurements.

pictured is a solid composite figure in the shape of a capital I. The length of the entire letter is 5 centimeters. The width is 2 centimeters. The height of the cross pieces at the top and the bottom is 2 centimeters. The length of the middle of the I is 2 centimeters long. Each distance from the outside edge of the middle piece to the outside edge of the top and bottom cross pieces is 2 centimeters.

Answer 4

Which most accurately describes the shape of the interior faces of this composite solid?

The figure consists of 2 solid shapes that resemble bricks connected at one corner, forming a right angle there. One shape has a length of 8 meters, a width of 7 meters, and a height of 7 meters. The other shape has a length of 7 meters, a width of 8 meters, and a height of 7 meters. Filling the corner formed by the right angle is a three-sided figure whose vertex fits into the right angle. The base of this figure is straight and connects the other 2 vertices of the bricks, which are at the outside of the right angle.

rectangles

squares

trapezoids

triangles

Answer 5

What is the total area of the interior faces of this composite solid?

The figure consists of 2 solid shapes that resemble bricks connected at one corner, forming a right angle there. One shape has a length of 8 meters, a width of 7 meters, and a height of 7 meters. The other shape has a length of 7 meters, a width of 8 meters, and a height of 7 meters. Filling the corner formed by the right angle is a three-sided figure whose vertex fits into the right angle. The base of this figure is straight and connects the other 2 vertices of the bricks, which are at the outside of the right angle.

Answer 6

im not good in this subject

Answer 7

I'm not good at this subject either.. this is Math, but it's posted in the Biology section. I can help with Biology, but not with Math, lol. :p
Also, remember to post only one question per thread, as it is against the CoC to post multiple questions within one thread.
I'm saying this because I don't want you to get in trouble, okay? (:
And I'm sorry that I couldn't be of more help. :s
