Graham carves a block of wood shaped like a cube with a square pyramid on top of how much paint Will Graham made to paint the toy

913 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the toy is equal to the area of five faces of the cube (4 lateral faces plus the base) plus the area of four lateral triangles of the pyramid

so

we have

substitute

therefore

Graham will made 913 square centimeters of paint

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

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.
