Question

DWACRA IS SUPPLIED CUBOIDAL SHAPED WAX BLOCK WITH MEASUREMENTS 88CM × 42CM × 35CM.FROM THIS HOW MANY NUMBER OF CYLINDRICAL CANDLES OF 2.8CM DIAMETER AND 8CM OF HEIGHT CANBBE PREPARED

Answer 1

2625 cylindrical candles can be prepared

Answer 2

Answer:

2625

Step-by-step explanation:

Length of block = 88 cm

Width of block = 42 cm

Height of block = 35 cm

Volume of block = $Length \times Height \times width = 88 \times 35 \times 42 =129360cm^3$

Diameter of candle = 2.8 cm

Radius of candle = $\frac{2.8}{2}=1.4 cm$

Height of candle = 8 cm

Volume of candle = $\pi r^2 h = \frac{22}{7} \times 1.4^2 \times 8 = 49.28 cm^3$

No. of candles formed = $\frac{129360}{49.28}=2625$

Hence 2625 candles are formed
