a box is a cuboid with dimensions 28cm by 15cm by 20cm to the nearest centimetre
disc cases are cuboids which measure 1.5cm by 14.2cm by 19.3cm all measured to nearest millimetre
show that 17 disc cases will definitely fit in the box

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

it is not that hard all u have to do is plot the graph

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
