Answer:

The characteristics of a good math explanation are following:

1. Step by step explanation: The first characteristics of a good math explanation is step by step solution. Do not skip steps because the assumption that the other person knows what you did is not always correct.

2. Justify each step: Mention the reasons behind each step, i.e, theorem, formula, rule etc.

3. Result verification: After find the solution the last step is to verify the solution.

We need to check whether the solution fulfills the given conditions or not. If it satisfy all the given conditions, then it is correct otherwise we need to check our work.

Find the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm

FromTheMoon [43]

Answer:

The surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.

Step-by-step explanation:

Slant height of square pyramid = l = 13 mm

Base length of square pyramid = b = 11 mm

Formula of surface area of square pyramid = $b^2+2bl$

Substitute the values in the formula :

Surface area of square pyramid = $11^2+2(11)(13)$

Surface area of square pyramid =407 sq.mm.

Hence the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.
