Q 1 - The region of the base of a rectangular tank is 6500 cm2 and the volume of the water contained in it in 2.6 cubic meter. The profundity of the water in the tank is:
L*b= 6500cm2 , L*b*d=2.6m3=(2.6*100*100*100) cm3 ∴ d = (2.6*100*100*100)/6500 cm = (2.6*100*100*100)/6500*100 = 4m ∴ Depth = 4m
Q 2 - An open box is comprised of a metal. It is 50cm long, 40cm expansive and 23 m high. The thickness of the metal is 3cm. In the event that 1 cubic cm of the metal weighs 0.5 gm, then what is the heaviness of the void box?
Volume of metal = [(50*40*23)-(44*34*20)]c m3 = 46000-29920= 16080 cm3 Weight of metal = (16080*5/10*1/1000) kg = 8.04 kg Weight of the empty box = 8.04 kg
Q 3 - If the territory of three adjoining countenances of a cuboid is x, y, z separately, At that point the volume of the cuboid is:
Let the length of cuboid = L, Breadth = b and height = h Lb=x, bh= y and Lh= z ∴ xyz = L2b2h2⇒Lbh = √xyz ⇒volume =√xyz.
Q 4 - The surface territory of a (10cm *4cm*3cm) block is:
Here L =10 cm, b= 4 cm, h = 3cm Surface area = 2(Lb+bh+Lh) = 2(10*4+4*3+10*3) cm2 = 2*82 = 164cm2
Q 5 - If every side of a solid shape is multiplied, then its volume:
Let the edge of the original cube be x. Then its volume = x3 New edge = 2x, new volume (2x) 3=8x3 So, it?s become 8 times.
Q 6 - The aggregate surface zone of 3D square (cube) is 1734 cm2 .Its volume is:
6a2=1734 ⇒a2=289= (17) 2 ⇒a= 17 Volume = a3= (17*17*17) cm3= 4913cm3
Q 7 - If every side of a 3D square of volume v is multiplied, its volume gets to be ℏv where ℏ is equivalent to:
Let each side be a, then, V= a3 New volume = (2a) 3= 8a3= 8V ∴ℏV= 8V⇒ℏ= 8
Q 8 - Water streams out through a round funnel whose inner measurement is 2cm, at the rate of 6 meters for each second into a barrel shaped tank, the range of whose base is 60 cm. By what amount will the level of water ascend in 30 minutes?
Length flown in 30 minutes = (6*60*30) m = 10800 m r = 1/100m, h = 10800 m Volume = (π*1/100*1/100*10800) m3 Let the height of the water level be h meters. Then, π*60/100*60/100*h = π*1/100*1/100*10800 ⇒ h = (108/100*5/3*5/3) = 3m
Q 9 - A empty greenery enclosure roller 63cm wide with a circumference of 440 cm is made of iron 4 cm thick. The volume of the iron utilized is:
2πr= 440 ⇒2*22/7*r= 440 ⇒r= (440*7/44) = 70 cm Outer radius = 70cm, inner radius = (70-4) = 66cm Volume of iron = π [(70)2-(66)2*63cm3= (22/7*136*4*63) = 58752 cm3
Q 10 - If the radii of the two circles are in the proportion 1:4, then their surface regions will be in the proportion?
Let their radii be rand 4r. Ratio of their surface areas= 4πr2/4π (4r) 2= r2/16 r2= 1/16= 1:16
