Answer:

Step-by-step explanation:

Six liters of paint will cover 50 square meters.

6L ⇒ 50m²

then,

1L ⇒ 50/6 m²

9L ⇒ 50 × $\frac{9}{6}$ m²

⇒ 75 m²

Step-by-step explanation:

$adj \: = 5 \\ opp \: = 20 \\ hyp \: = \: \\ pythagoras \: theorem \: \: = \\ {hyp}^{2} = {opp}^{2} + {adj}^{2}$

${hyp \:}^{2} = {20}^{2} + {5}^{2} \\ {hyp }^{2} = 400 + 25 \\ {hyp}^{2} = 425 \\ \sqrt{ {hyp}^{2} } = \sqrt{425}$

Determine the lateral and total surface area

Kobotan [32]

The areas of the square pyramid are the amount of space on it

The lateral surface area is 292.5 square cm
The total surface area is 354.85 square cm

<h3>How to determine the lateral surface area?</h3>

The given parameters are:

Base (b) = 15 cm

Slant height (l) = 13 cm

The lateral surface area is calculated using:

L = 1.5bl

So, we have:

L = 1.5 * 15 * 13

Evaluate the product

L = 292.5

<h3>How to determine the total surface area?</h3>

This is calculated using:

T = L + 0.25√3b^2

So, we have:

T = 292.5 + 0.25√3 * 12^2

Evaluate

T = 354.85

Hence, the total surface area is 354.85 square cm
