Answer:
B) Cube
Step-by-step explanation:
A) square pyramid has one square base and 4 congruent triangles
B) Cube has 6 congruent squares
C) Rectangular pyramid has one rectangle base and 4 congruent triangles
D) Rectangular prism has 3 sets of rectangles; total of 6 rectangles
Let the width of the rectangle be x
Then length =x-4
Area=x(x-4)=140
x²-4x=140
x²-4x-140=0
x²-14x+10x-140=0
x(x-14)+10(x-14)=0
(x-14)(x+10)=0
Therefore,length=14 cm and width=10 cm
You can do:
6x7000 then
6x300 then
6x80 then
6x1 then
you add all the product.
