Find the lateral area for the pyramid with the equilateral base

likoan [24]

<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>

Solution:

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

Find the perpendicular

By Pythagoras theorem

$hypotenuse^2 = opposite^2 + adjacent^2$

Therefore,

$opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8$

Find the lateral surface area of 1 triangle

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base$

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48$

Thus, lateral surface area of 3 triangle is:

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units

2 1/4 ⋅ 1 2/3 as a mixed number

Gemiola [76]

Answer:

$3\frac{3}{4}$

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

$\frac{9*5}{4*3}$

$\frac{45}{12}$

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

$3\frac{3}{4}$

What is the total surface area of the drawing?

Soloha48 [4]

Total surface area equals area of 5 rectangular faces + 2 pentagonal faces

Area of 5 rectangular faces

$=5 \times 6 \times 9 km^2$

$=270 km^2$

Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.

$=5 \times \frac{1}{2} \times 9 \times 6.2 \times 2km^2$

$=279km^2$

The toatal surface area is

$=270+279=549 km^2$

The correct answer is A
