Answer:

Hence required paper for entire shape will be L[L+2(2H+H1)] Sq.cm

Step-by-step explanation:

Given:

A block with rectangular prism at bottom and square pyramid at top.

To Find:

Paper required to cover whole block

Solution:

We know that block consist of two different shapes as prism and pyramid.

So paper covering will be for surface.

hence we required surface area for rectangular prism and square pyramid.

(Refer the attachment)

Now only outer surface should be consider in order to cover the shape.

for square pyramid its length and breadth will be the same .

let L be length and B be breadth and h be height

<em>So total no.of faces will be 6 but on top there is prism placed so top surface will be neglected for the calculations</em>.

H<em>ence No.of faces will be 5.</em>

So total surface area for square pyramid  will be

=L*W+2(L*H+W*H)

Here L=W as it is square pyramid

=L^2+4(L*H)

Now for the Prism surface it will  have 4 triangles placed on with base as length of pyramid(as shown in fig) and height be H1

So Total area for Prism will be

=4( Area of triangles)

=4*1/2*base*height)

=2*base *height

=2*L*H1

So required Paper will be

Total surface area=Surface are of pyramid+ Area of 4 triangles.

=L^2+4(L*H)+2*L*H1

=L[L+2(2H+H1)].

The ratio of the same side interior angles of two parallel lines is 33:3. Find the measures of all eight angles formed by the pa
zheka24 [161]

9514 1404 393

Answer:

  all 4 acute angles: 15 degrees

  all 4 obtuse angles: 165 degrees

Step-by-step explanation:

The sum of same-side interior angles between parallel lines is 180°. The smallest of them will be 3/(33+3) = 1/12 of 180°, or 15°. The largest will be 180° -15° = (33/3)(15°) = 165°. All remaining angles are congruent to one or the other of these.

  All four acute angles are 15°; all four obtuse angles are 165°.
