Find the surface area of the prism below. See attachment, 58 cm is incorrect.

Masja [62]

Answer:

Surface area of the given figure = 48 cm^2

Step-by-step explanation:

Surface area is nothing area of all the sides.

We can find the area of each figure add them together.

There are two triangles with the same measures.

One rectangle with measure of 4 by 3.

Another rectangle with the measure of 5 by 3.

One square with the measure of 3.

Surface area = Area of two triangles + rectangle 1 + rectangle 2 + square

Formulas:

Area of the triangle = 1/2 base* height

Area of the rectangle = length * width

Area of the square = side x side

Applying the formula, we get

=2[1/2 (3*4)] + 4*3 + 5*3 + 3^2

= 12 + 12 + 15 + 9

Surface area of the given figure = 48 cm^2

Hope this will helpful.

Thank you.

Donnel practiced the piano 3 hours longer than Marcus. Together they practiced the piano for 11 hours. How many hours did each b

andriy [413]

Here is the equation: $x+(x+3)=11$ ⇒ $x+x+3=11$

You need to get "x" by itself so minus 3 from each side

$x+x+3-3=11-3$ ⇒ $x+x=8$ ⇒ $2x=8$

Divide 8 by 2

$8$ ÷ $2=4$

x=4

So each 4 is equivalent to 4

Lets check:

$4+(4+3)=11$ ⇒ $4+4+3=11$ ⇒ $11=11$

So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
