Liam, Sarah and Emily shared some money in the ratio 2:3:5. Liam got £30 less than Sarah.

blondinia [14]

The number representing Liam's share is 2; for Sarah's share, it is 3. The difference of those is 1, so each 1 unit of share must be £30, the difference between the amount Sarah got and the amount Liam got.

Emily got 5 shares or £30 × 5 = £150.

Find the surface area of a rectangular prism measuring<br> 5 m by 8 m by 9 m.

olganol [36]

The formula of the surface area of the rectangular prism is equal:
$A=2(wl+wh+lh)$
where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
$A=2\cdot(5\cdot8+5\cdot9+8\cdot9)=2\cdot(40+45+72)=2\cdot157=314\ m^2$
