The prism has a volume of 120 cm3. What would the volume of the prism be if each dimension were halved? cm3 Triangular prism wit
Citrus2011 [14]
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3

Alik [6]

Answer:

No. She should have multiplied 12 and One-half to solve

6 yards

Step-by-step explanation:

Number of girls = 12

Each girl needs = 1/2 yard of strings

Suzie workings:

12/1 ÷ 1/2

= 12/1 × 2/1

= 24/1

= 24 yards

No. She should have multiplied 12 and One-half to solve

Correct workings:

Total strings needed for 12 girls = 12 × 1/2 yards

= (12*1)/2

= 12/2

= 6 yards
