NEED ASAP! A contractor poured concrete to form the set of steps shown below. Each step rises 8 inches and is 10 inches deep. The image shows a set of 3 steps with width, length and breadth as 8 in., 10 in., and 36 in. respectively. Question What volume of concrete did the contractor use? A. 8,640 cubic inches B. 17,280 cubic inches C. 18,432 cubic inches D. 25,920 cubic inches

i think the amount would be $140.62

answer

step-by-step explanation:

i don't see any steps below, sweetheart

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
