CAN SOMEONE PLSSS HELP ME! IT’S DUE TODAY. I NEED THE SURFACE AREA AND VOLUME...
aev [14]

Answer:

Surface \ area = 2 (LB + BH + HL) = 2 ((4\times 8)+(8 \times 6) + (6 \times 4))

                                                     = 2(32 + 48 + 24)\\=2(104) \\=208 cm^2

Volume = L \times B \times H = 4 \times 8 \times 6 = 192cm^3

<h3>What is the  Pythagoras theorem?</h3>

Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle.

It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.

The given data in the problem will be;

L is the length of ramp=  10 feet

x is the horizontal distance from the bottom of the ramp = 8 feet

h is the height from the ground to the top of the ramp=?

According to Pythagoras theorem,

\rm H^2=P^2+B^2 \\\\  \rm l^2=h^2+X^2 \\\\ \rm 10^2=h^2+8^2 \\\\ \rm h=\sqrt{100-64 }  \\\\ \rm h=36 \\\\  \rm h=6 ft

Hence the height from the ground to the top of the ramp 6. 0 ft. Option D is correct.
