What is the surface area and volume? PLEASE EXPLAIN IN DETAIL.
Effectus [21]

Check the picture below.

so to find the surface area of the triangular prism, we simply add the areas of each of the figures composing it, as you can see is really just 2 triangles an 3 rectangles.

\bf \stackrel{\textit{\Large Areas}}{\stackrel{triangles}{2\left[ \cfrac{1}{2}(4)(3) \right]}+\stackrel{\textit{rectangles}}{(3\cdot 10)+(4\cdot 10)+(5\cdot 10)}}\implies 12+30+40+50\implies 132

now, to get the volume is simply the area of the triangular face times the length, well, we know the area of one of the triangles is 6, times 10 is just 6*10 = 60.

What is the product of (-4)(7) and why?
Mumz [18]

Answer:

The product of (-4)(7) is -28 because you are removing 4 times, the number 7

.

Reason is below.

Step-by-step explanation:

The number which is written first in the multiplication or the product is always multiplied by the second number.

For example

3 × 2 implies three times two which equal to 6

2 × 3 implies two times three which is also equal to 6

Therefore the number written in the first is count as times, the number second.

For example

-3 × 2 implies three times two which equal to -6

Here the product is negative 6

Because if a negative number is multiplied by positive number you will always get the product as negative number.

If a positive numbers multiplied by positive number you will always get the product as a positive number.

For example

3 × 2 implies three times two which equal to 6

If a positive numbers multiplied by negative number you will always get the perfect as a negative number.

For example

3 × -2 implies three times two which equal to -6

If a negative number is multiplied by negative number you will always get the product as a positive number.

For example

-3 × -2 implies three times two which equal to 6

Therefore, the product of (-4)(7) is -28 because you are removing 4 times, the number 7
