Two solids have the same height. Figure A has a cross-section that is a triangle with a base of 12 ft and a height of 10 ft while figure B has a cross-section that is a trapezoid with bases of 6 ft & 12 ft and a height of 10 ft. Which of the following is true? (A) Figure A has a larger volume (B) Figure B has a larger volume (C) The figures have equal volumes

jjj

the answer is 175.4379

step-by-step explanation:

28

step-by-step explanation:

8+8+6+6

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
