Question

Two (big and small) garbage blocks are organized by stacking them on top of each other. Find the height of the big grabage block.

• A. $\left(6.232\right)\times {10}^6\text{inches}$
• B. $\left(62.32\right)\times {10}^6\text{inches}$
• C. $\left(623.2\right)\times {10}^6\text{inches}$
• D. $\left(6.232\right)\times {10}^6\text{inches}$

Answer 1

The correct option is A $\left(6.232\right)\times {10}^6\text{inches}$

Given:
The total height of the garbage blocks = $6.25\times {10}^6$ inches
The height of the small garbage block} = $1.8\times {10}^4$ inches

Total height = Big block + Small block

$\Rightarrow$ Big block = Total block - Small block

= $6.25\times {10}^6$ inches - $1.8\times {10}^4$ inches

= $625\times {10}^4$ inches - $1.8\times {10}^4$ inches

= $(625-1.8)\times {10}^4$ inches

= $\left(623.2\right)\times {10}^4$ inches

= $\left(6.232\right)\times {10}^6$ inches

$\therefore$The height of the big grabage block is $\left(6.232\right)\times {10}^6$ inches.
