100/5= 20
20 x 4 = 80
80 + 43 = 123
if my math is correct then none are correct
(prolly a typo)
Answer:
640 feet cubed
Step-by-step explanation:
Volume=length x width x height
V=8 x 10 x 8
V=640
Pythagoras, cool.
30^2 is 900
15^2 is 225
26^2 is 676
676+225 isn't 900 so it isn't A.
10^2=100
26^2=676
24^2=576
100+576=676 so B is a right angled triangle.
Hope this helps :)
