## Best 5th Grade **OST** Math Exercise Resource for 2021

## Answers:

1- **D**

Use volume of cube formula.

Voluem\(=\) length \(×\) width\( ×\) height\( ⇒ V= 6 × 4 × 8 ⇒ V=192 \space\)\( cm^3\)

2- **D**

Find the area of the room which is a square. Use area of square formula.

\(S= a^2 ⇒ S= 18\) feet \(× 18\) feet \(= 324\) square feet

3-** D**

Use percent formula:

part\( =\frac{percent}{100}× \)whole

\(600 =\frac{percent}{100}× 2400⇒ 600=\) percent \(× 24 ⇒\)percent\(=25 \)

4- **A**Use area of rectangle formula.

\(A= a × b ⇒ A= 54 × 12 ⇒ A= 648\)

Divide the area by 9 (\(3 × 3 = 9\) squares) to find the number of squares needed. \(648 ÷ 9 = 72\)

5- **C**

ABC Corporation’s income \(= \frac{2}{3}\) management’s predicted income.

\($200,000 = \frac{2}{3}\) management’s predicted income

management’s predicted income \(= $200,000×\frac{3}{2} =$300,000\)

6- **A**

Write the numbers in order:

\(9, 9, 10, 11, 13, 14, 18\)

Median is the number in the middle. Therefore, the median is 11.

7- **29**

Use PEMDAS (order of operation):

\(9 + [8 × 5] ÷ 2 = 9 + (40) ÷ 2 = 9 + (40 ÷ 2) = 29\)

8- **B**

Write the numbers in order:

\(4, 5, 8, 9, 13, 15, 18\)

Median is the number in the middle. Therefore, the median is 9.

9- **500**

Use volume of cylinder formula.

Voluem\(=\) base \(×\) heigth \(⇒ V=50 × 10 ⇒ V=500\)

10- **C**

13 yards long rope is cut into 4 equal parts. Therefore, 13 should be divided by 4. Only option C is NOT 13 divided by 4. (It is 4 divided by 13)
