Answer:
2d or 2 dimensional is the answer i think
Step-by-step explanation:
since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together
D = m/v
V = 2•2•2 = 8cm^3
D = 12/8 = 1.5g/cm^3
Answer is B
Answer:
Area = 36 sq units
Step-by-step explanation:
An isosceles trapezoid have two triangles and probably a rectangle or a square.
To find the area, let's determine the height of the trapezoid.
The base length of one of the triangle
= (15-9))2
= 6/2 = 3
The height will be x
X /sin 45= 3 / sin 45
X= 3
The area of the trapezoid
= 1/2(a+b)h
Where a = 15
b = 9
h = 3
Area= 1/2(15+9)3
Area= 1/2 *24*3
Area= 12*3
Area = 36 sq units
