The attic floor, ABCD in the model, is a square. The beams that support the roof are the edges of a block (rectangular prism) EF
morpeh [17]

Answer:

EF = 6m.

Step-by-step explanation:

Given that:

1) All the edges of the pyramid in the model have length 12m.

So, AB = 12m

2) E is the middle of AT, F is the middle of BT

So, EF is a line segment connecting the midpoints of ΔATB

So, by applying The Triangle Mid-segment Theorem

EF // AB and EF = 0.5 AB

So, EF = 0.5 AB = 0.5 * 12 = 6m

====================================

The Triangle Mid-segment Theorem:

The line segment connecting the midpoints of any two sides of a triangle has the following properties:

1) The line segment will be parallel to the third side.

2) The length of the line segment will be a half of the length of the third side.

Nataliya [291]

The total weight of Nico's diamond is 564 ounces

<h3>Weights</h3>

The weights of the diamond are given as:

5, 13, 12, 4, 9, 8, 15, 210, and 6 ounces

<h3>Total weights</h3>

Start by calculating the total weights

Total = 5+13+12+4+9+8+15+210+6

Total = 282

The above sum represents the total weights of Jack's diamonds.

So, the total weights of Nico's diamond is calculated as:

Nico = 2 \times 282

Nico = 564

Hence, the total weight of Nico's diamond is 564 ounces
