Answer:

288 cm²

Step-by-step explanation:

The square base has an area of 64 cm².

That means the sides of the square base measure 8 cm.

The perimeter of the base is P = 4 * 8 cm = 32 cm.

The lateral area is Ph = 32 cm * 5 cm = 160 cm².

The two bases are congruent, and their combined area is 2 * 64 cm² = 128 cm².

The total surface area equals the sum of the lateral area and the area of the bases.

SA = 160 cm² + 128 cm²

SA = 288 cm²

Answer:

total surface area of cube is <u>6 * area of one side</u>

therefore area of one side is given 64cm^2

Rewrite, using the distributive<br> property.<br> 5(2x – 3y) = [?]* - [ ]y
olchik [2.2K]

Answer:

10x-15y

Step-by-step explanation:

So, when they say use the distrubutive property, they basically mean turning this:

a(b+c)

Into this:

ab+ac

So in this case, it would be:

5(2x-3y)

And we will turn it into:

10x-15y

ANother way to think about it is we are multiplying 2x by 5, and -3y by 5. So:

2x*5

=

10x

And

-3y*5

=

-15y

Then we can combine these two:

10x-15y

Hope this helps!
