Formula of surface area of cuboid = 2(lb+bh+lh) . Surface area of cuboid is 14800cm^2 (Given) then 14800 = 2(60*40+40*Height+Height*60) 14800= 2(2400+40*H+H*60) 14800= 4800+80*2H+2H*60 14800= 4880*4H*60 14800/4880*60= 4H
14800/292800=4H
7400/146400=4H
3700/73200=4H
1850/36600=4H
925/18300=4H
185/3660=4H
37/732=4H
37/732*4=H
37/2928=H
H= 79.1351351
Answer:
Step-by-step explanation:
you multiply across, so you do 2*2 for the numerator, then 3*3 for the denominator. This would equal 4 as the numerator, 9 as the denominator, which is
12b-15>21
+15 +15
12b > 36

Answer:
D. If a shape is an equilateral triangle, then it is an isosceles triangle.
Step-by-step explanation:
Answer:
solution:Here
Given,
Load=800 N
Load distance=2cm
Effort distance=260cm
Effort applied=?
We know that,
Load × Load distance = Effort × Effort distance
or, 800×2 = e × 260
or,1600 = 260e
or,e = 1600/260
Thus, e = <u>6.15</u><u> </u><u>N</u>
<u>Hence</u><u>,</u><u> </u><u>The</u><u> </u><u>effort</u><u> </u><u>applied</u><u> </u><u>=</u><u> </u><u>6.15</u><u> </u><u>N</u>
