You have to round it to 21 which is the answer
Length=3
Width=4
Height=3
There are 36 cubes in this prism.
The volume is 36 ft
The surface area of the prism will be given by:
SA=(surface area of triangles)+(surface area of rectangles)
surface area of triangles=2(1/2*3*4)=12 sq. units
area rectangles
the length of the hypotenuse will be:
c²=a²+b²
c=√(3²+4²)
c=√25
c=5
area=(3*5)+(4*5)+(5*5)=60
Total area=60+12=72 sq. units
Answer: 72 sq. units
