Simplify 5/8×8 and explanation thanks.

Paha777 [63]

Explanation: Since 5/8 x 8 can be answered (because there is no variable), turn the whole number "8" into a fraction which would be: 8/1. Now, 5/8 x 8/1 equals 40/8 because 5 x 8 = 40 and 8 x 1 = 8. Now, simplify 40/8, which would be 20/4, simplifying it, even more, would be: 10/2, and one more time: 5/1 which is equivalent to 5. Hope this helps!

Find the surface area

Semmy [17]

Answer:

The surface area is $198.75\ ft^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the bottom</u>

$A = s^2$

$A = (7.5\ ft)^2$

$A = 56.25\ ft^2$

<u>Step 2: Determine the area of the triangles</u>

$A = \frac{h * b}{2}$

$A = \frac{9.5\ ft * \frac{7.5\ ft}{2}}{2}$

$A=\frac{9.5\ ft*3.75\ ft}{2}$

$A = 17.8125\ ft^2$

There are two of these right triangles on every side which means that we have 8 of these triangles so we multiply the area that we got by 8.

$A = 17.8125\ ft^2 * 8$

$A=142.5\ ft^2$

<u>Step 3: Combine the area to get the surface area</u>

$A_{total}=56.25\ ft^2+142.5\ ft^2$

$A_{total}=198.75\ ft^2$

Answer: The surface area is $198.75\ ft^2$
