Answers

Primary 5 Mathematics Quiz – Measurement: Answer Key

Answer 1.

C) 2 400 ml. ( $2.4 \times 1000 = 2\ 400$ )

Answer 2.

C) $125^\circ$ . ( $360 - 145 - 90 = 125$ )

Answer 3.

C) $125\ cm^3$ . ( $5 \times 5 \times 5$ )

Answer 4.

C) $42\ cm^2$ . ( $\frac{1}{2} \times 12 \times 7$ )

Answer 5.

B) $68^\circ$ . Vertically opposite angles are equal.

Answer 6.

Angle COB = $180^\circ - 118^\circ = 62^\circ$ . (Angles on a straight line add up to $180^\circ$ .) [3 marks]

Answer 7.

(a) Volume = $8 \times 5 \times 4 = 160\ cm^3$ . [2 marks] (b) Since $1\ cm^3 = 1$ ml, the volume is 160 ml. [1 mark]

Answer 8.

Height = $(36 \times 2) \div 9 = 72 \div 9 = 8$ cm. [3 marks]

Answer 9.

(a) 4 700 m (b) 6.08 kg (c) 3 080 ml [1 mark each]

Answer 10.

Angle PQR = Angle PRQ = $(180 - 52) \div 2 = 128 \div 2 = 64^\circ$ each. (Base angles of an isosceles triangle are equal.) [3 marks]

Answer 11.

Volume of water = $30 \times 20 \times 8 = 4\ 800\ cm^3$ . Convert: $4\ 800 \div 1\ 000 = 4.8\ \ell$ . [3 marks]

Answer 12.

Bottom = $40 \times 25 = 1\ 000\ cm^2$ . Front and back = $2 \times (40 \times 20) = 1\ 600\ cm^2$ . Sides = $2 \times (25 \times 20) = 1\ 000\ cm^2$ . Total outer surface area = $1\ 000 + 1\ 600 + 1\ 000 = 3\ 600\ cm^2$ . [3 marks]

Answer 13.

(a) Angle C = $180 - 90 - 35 = 55^\circ$ . (Angle sum of a triangle.) [1 mark] (b) Area = $\frac{1}{2} \times 10 \times 6 = 30\ cm^2$ . [2 marks]

Answer 14.

Volume of cube = $6 \times 6 \times 6 = 216\ cm^3$ . Volume stays the same after melting. Height of cuboid = $216 \div (9 \times 8) = 216 \div 72 = 3$ cm. [3 marks]

Answer 15.

$x + 2x + 3x = 180$ , so $6x = 180$ , giving $x = 30$ . Largest angle = $3 \times 30 = 90^\circ$ . [3 marks]

Answer 16.

Number of bottles = $18 \div 1.5 = 12$ bottles. [2 marks]

Answer 17.

$2.75\ m = 275$ cm. Number of pieces = $275 \div 25 = 11$ pieces. [2 marks]

Answer 18.

Base = $(48 \times 2) \div 8 = 96 \div 8 = 12$ cm. [2 marks]

Answer 19.

Angles at a point add up to $360^\circ$ : $y = 360 - 150 - 95 = 115$ , so $y = 115^\circ$ . [2 marks]

Answer 20.

Total volume = $50 \times 30 \times 40 = 60\ 000\ cm^3$ . Remaining water = $60\ 000 - 6\ 000 = 54\ 000\ cm^3$ . New depth = $54\ 000 \div (50 \times 30) = 54\ 000 \div 1\ 500 = 36$ cm. [2 marks]
