Work out the surface area of the solid cuboid.
8m
5m
2m

Step-by-step explanation:

T.S.A=2(LXW) + 2(LXH) + 2(WXH)

=2(8mx5m) + 2(8mx2m) + 2(5mx2m)

=(2x40m²) + (2x16m²) + (2x10m²)

=80m² + 32m² + 20m²

=132m²

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

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
