Work out the surface area of the solid cuboid. 2.5m 2m 5m The diagram is not drawn to scale.

the formula for TSA of a cuboid is (lb+bh+hl)

soo it will be

(2.5x2+2x5+5x2.5)

(5+10+10)

(25)

so 25 cm^2

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
