There are four triangles and one square, the areas of which can be added together to form the total surface area.
Area of triangle = 0.5bh
= 0.5*16*15
= 120 cm^2
Since there are four triangles, the total area for them would be 120*4 = 480 cm^2
Area of square = 16^2 = 256
Total surface area = 256 + 480 = 736 cm^2
Answer: it should be 252 in.
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
since it can be expressed as a fraction, it is rational
A and B
8/16 = 1/2
A=1/2
B=2/3
C=1/2
D=1
We must calculate 3 (1/2) minus 1 (4/5)
We must make the denominators equal So it becomes
3 (5/10) minus 1 (8/10) which equals
2 (-3/10)
That is an improperly formatted fraction so we reformat it:
1 (7/10)
