Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=

base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
Answer:
two cubes one 24 m per side one 7m per side
Step-by-step explanation:
24 x 6 = 144 + 7 times 6 = 186
vs
25 times 6 = 150
Answer:
x=4
Step-by-step explanation:
First you add the values with x and theese without x:
(3x+8x+7x)+(9-6-2)=73
18x+1=73
Then you subtract (-1) from both sides:
18x=72
And then you divide by 18:
x=72:18=4
Answer: 73
