Aset of small building blocks contains 48 blocks. the blocks are cube-shaped and have an edge length of 1/2 inch. if all the blocks in the set are used to build a rectangular prism, what is the volume, in the cubic inches, of the rectangular prism

6 in^3

Step-by-step explanation:

Each block is a cube with edge length of 1/2 inch.

V = s^3

V = (1/2 inch)^3

V = 1/8 inch^3

Each cube has a volume of 1/8 cubic inch.

48 blocks have 48 times the volume of one block.

volume of prism = 48 * 1/8 in^3

volume of prism = 6 in^3

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
