Concrete is poured to make a pathway.

The dimensions of the slab are shown in the diagram below.

If the concrete costs $180 per cubic metre to pour, what is the cost of pouring the slab?

$A$

Show Worked Solution

$30\ \text{cm}=0.3\ \text{m}$

$\text{Volume of slab}$	$=8\times 0.3\times 2$
	$=4.8\ \text{m}^3$

$\text{Cost of pouring slab}$	$=4.8\times $180$
	$=$864$

$\Rightarrow\ A$

\(\text{Volume of slab}\)	\(=8\times 0.3\times 2\)
	\(=4.8\ \text{m}^3\)

\(\text{Cost of pouring slab}\)	\(=4.8\times $180\)
	\(=$864\)
