Question 1011569
.
The base of the solid figure shown is a cube with sides that measure 6 inches. The top portion is a square pyramid 
with a slant height of 5 inches. The total height of the figure is 10 inches. What is the total surface area of the solid?
-------------------------------------------------------------------

<pre>
The surface area of the lower portion of the solid consists of the surface areas of 5 squares 6x6 inches each, 
so it is 5*6*6 = 180 square inches.

The top portion surface area consists of four triangles with the base 6 inches anf the height of 5 inches (slant height). 
So, the top portion surface area is 4*{{{1/2}}}.6*5 = 60 square inches.

The total surface area is 180 + 60 square inches, which is 240 square inches.

Answer is a).

<U>Notice</U>. One condition is excessive. 


Taking into account that the base is the cube with the side &nbsp;6&nbsp; inches, &nbsp;these two phrases
&nbsp;&nbsp;&nbsp;&nbsp;"The top portion is a square pyramid with a slant height of 5 inches". &nbsp;&nbsp;and 
&nbsp;&nbsp;&nbsp;&nbsp;"The total height of the figure is 10 inches"
carry the same information.
