Question #238c9

Answer 1

`420cm^3`

Explanation:

Split the block into 2 halves

length `xx` width `xx` height`=volume`

So: bottom halve`=10cm xx 8cm xx 3cm=240cm^3`

top halve: to get the height subtract 3cm from 6cm

So: top halve`=10c xx 6cm xx 3cm=180cm^3`

Total volume of block`=240cm^3+180cm^3=420cm^3`
