Answer is D
if you want to get the area of a triangle you have to multiply the base times height and than divide by 2
A= 1/2 bh
A=1/2 (7x6)
A= 1/2(42)
A= 21
and for the area of the rectangle it’s 42 since there’s no dividing
A=bh
A=7x6
A=42
Answer:
1 Expandir.
-28=-21x-28+21x
−28=−21x−28+21x
2 Simplifica -21x-28+21x−21x−28+21x a -28−28.
-28=-28
−28=−28

Step-by-step explanation:
Given that the volume of the prism is given by:
10 cubic units and the the side length of cubes to fill the prism is 1/2 units. Then the number of cubes required to fill the prism will be given by:
(volume of rectangular prism)/(volume of cube)
but
volume of cube is:
volume=length*width*height
volume=1/2×1/2×1/2=1/8 cubic units
thus the number of cubes required to fill the prism will be:
10/(1/8)
=10×8/1
=80 cube
Answer: 80 cubes
