**Solution:**

T- TOP

S- SIDE

F- FRONT

Find the

**Lenth**and**Width**for each one.Top- 5 (width) 10 (length)

Side- 6 (width) 5 (lenth)

Front- 6 (width) 10 (length)

Then multiply them

5

**x**10 = 506

**x**5 = 306

**x**10 = 60After you get the answer, add them together.

50 + 30 + 60 =

**140**Then multiply it by 2, you get

*280m²*So, your answer is

*280m²***Solution:**

Find the sides of the Triangle.

First side- 5 (length) 10 (width)

Second side- 5 (length) 9 (width)

Last side- 5 (length) 8 (width)

After you get the

**Length**and**Width,**add them all up.10 + 9 + 8 =

*27cm*When you get the answer, multiply the answer by the

*length.*27 x 5 =

*135cm²**Now, find the bxh.*

*9 (height) 8 (base)*

**B x H * 2**( * - divide )*9 x 8 = 72*

*Now, divide 72 by 2.*

*Answer-*

**36cm**

Take 135cm² and add 36cm twice.

*135 + 36 + 36 =*

**207cm²**

**207cm²****(**answer**)****Solution:**

Find the top circle of the Cylinder and the bottom.

The diameter of the circle is 8. You have to find the Radius, by

*dividing*the diameter by 2.8 (diameter) * 2 = 4 (radius)

Now, find the body of the

*Cylinder*.The width of the rectangle (body) is 12mm

Find the

**by multiply the pi and the diameter.***circumference**3.14 x 8*

*C =*25.12mm

*Now,*find the area of the rectangle.

Length x Width

25.12 x 12 =

**301.44mm²**

After that, find the Area of the circle.

Pi x radius²

3.14 x 4²

3.14 x 16

=

**50.24mm²**

Now, the body (rectangle) and the area of the cirlce, add all them up. But you need to add up the answer from Area of the circle.

*301.44 + 50.24 + 50.24*

*=*

**401.92mm²**

**Volumes:**

*Volume of Triangle*Formula:

Area of base *multiply* height

Find the base and the height

base- 3cm

height- 5cm

Now find the other height. The

**height**is 8.5cmMultiply the base and the height (bxh) after you get the answer, which 15. Then divide it

**2.****(15 divided by 2 )The answer is 7.5. Now multiply 7.5 to 8.5cm. Equals to****63.75cm³****Volume of Rectangle**

This formula is very easy. Just multiply the

**and the***Length***and the***Width**Height.*20x8x16 =

**2560cm³****Volume of Triangle with fraction**

*Formula:*The formula is the same as the Volume of Triangle.

But if there's a fraction with it, you have to do is, find the decimal of the fraction. (3*8=

**0.375cm)**After you get the decimal of the fraction, multiply it by the answer you got (104cm³)

104 x 0.375 =

*39cm**³***Volume of Cylinder**

*Formula:*d2 = r

12 * 2 =

**6**= radius

pi r2 x h

**3.14 x 6 x 6 x 15**

**3.14 x 36 x 15**

**=**

*1695.6cm³*
