Answer:
792m^2
Step-by-step explanation:
Seperate your 2 rectangles
Large one is 18*30
Small one (60-18)*6
18*30 = 540m^2
42*6=252m^2
Add the 2 values togetehr
Answer:
<h3><u>Question 7</u></h3>
<u>Lateral Surface Area</u>
The bases of a triangular prism are the triangles.
Therefore, the Lateral Surface Area (L.A.) is the total surface area excluding the areas of the triangles (bases).

<u>Total Surface Area</u>
Area of the isosceles triangle:

Total surface area:

<u>Volume</u>

<h3><u>Question 8</u></h3>
<u>Lateral Surface Area</u>
The bases of a hexagonal prism are the pentagons.
Therefore, the Lateral Surface Area (L.A.) is the total surface area excluding the areas of the pentagons (bases).

<u>Total Surface Area</u>
Area of a pentagon:

where a is the side length.
Therefore:

Total surface area:

<u>Volume</u>

Number of cubes increases by 3 for each term.
