Question

This square-based pyramid is made of wire.

The edges of the base all have length 3.07 cm.
The other edges all have length 6.93 cm.
Find the total length of wire.

Answer 1

Answer: 40cm

Explanation:

3.07 x 4 = 12.28

6.93 x 4 = 27. 72

12.28 + 27.72 = 40cm

Answer 2

40 cm

Explanation:

A square-based pyramid is a three-dimensional geometric shape with a square base and four congruent triangular faces that meet at a single point called the "apex".

The edges of a square-based pyramid consist of 4 congruent slant edges and 4 congruent base edges. The slant edges form the sides of the triangular faces, and the base edges connect the vertices of the base.

Given the edges of the square base are 3.07 cm, and the slant edges are 6.93 cm, the total length of the wire is:

`\begin{aligned}\sf Total\;length\;of\;wire&=\sf 3.07 * 4+6.93 * 4\\&=\sf 12.28+27.72\\&=\sf 40\; cm\end{aligned}`

Therefore, the total length of the wire is 40 cm.
