Question

A triangular prism has a volume of 10 cm3. If each dimension of the prism is multiplied by four, what is the new volume of the prism?

320 cm3

80 cm3

160 cm3

640 cm3

Answer 1

give me a sec to solve

Answer 2

thank u im redoing them to bost my grade

Answer 3

answer is 640 cm^3 how??? because
solution:
V= 1/2* l *w*h
given V = 10 cm^3
but here given ,
new vol= 1/2* 4l*4w*4h
=64 * 1/2* l*w*h
=64*V
=64*10
=640 cm^3

Answer 4

wow ur good can u help me again??

Answer 5

sure i'll try

Answer 6

Each dimension of a rectangular prism is increased by 30%. What percent of the original volume is the volume of the new prism?

9 percent

169 percent

2.7 percent

219.7 percent

Answer 7

ok wait lemme solve

Answer 8

answer is 219.7% how lets prove....

Answer 9

l*w*h = V
if we use
h= 2
w= 3
l= 4
V= 24 units^3
increase by 30%
we get,
h= 2.6
w= 3.9
l= 5.2
v =52.73 units^3
which is 219.7% time of the original volume
original volume * 219.7% => 24 * 219.7% = 52.728 hence proved
