Height=12,鈥�鈥�Slant鈥�鈥�Height=13

Short Answer

Expert verified

The sketch of the pyramid will be as shown

The lateral area, total area and volume of pyramid are.

Step by step solution

01

Step 1. Given information.

A square pyramid with height 12 and slant height 13.

02

Step 2. Sketch the pyramid.

Now to draw pyramid, first draw a parallelogram for the base and sketch diagonals and then draw a vertical segment at the point where the diagonal intersects and then join the vertex to the base vertices,

Thus, the pyramid can be obtained as:

03

Step 3. Interpretation.

Form the above graph and base edge and lateral edge it can be observed that the lateral area, total area and volume of pyramid are 260,360and 400.
