Question

If a box can hold 29 sweets, then what is the best way to estimate the number of sweets in 4 boxes?

• A. $4\times 20$
• B. $4\times 30$
• C. $4\times 300$
• D. $40\times 30$

Answer 1

The correct option is B $4\times 30$

A box can hold a maximum of 29 sweets. Thus, 4 boxes would have $4\times 29=116$ sweets, which is almost 120 sweets, which is nothing but $4\times 30$ sweets.
