This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find the value of the concrete used in the ramp if the cost of concrete is $3.00 per cubic foot. 6ft 6ft 10.2ft

$550.80

Step-by-step explanation:

Value of concrete used = volume of the prism x cost per cubic foot

volume of the prism = base area x height

the base is in the shape of a triangle

Area of a triangle = (1/2) x base x height = 1/2 x 6 x 6 = 18

Volume of the prism = 18 x 10.2 = 183.6 ft^3

183.6 x 3 = $550.80

answer: .75 km

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
