Answer:

If you think numbers with fractions are annoying, consider transforming the number into fractions!

Step-by-step explanation:

7 1/2 is (14+1)/2, and 3 1/8 is (24+1)/3. Not you have 15/2 miles for 25/3 days and by dividing them you get 0.9 miles a day

A rectangular prism has a base length of 6 units, base
Maurinko [17]

Answer:

The lateral area rectangular prism is 88 unit^2.

The area of the two bases of rectangular prism together is  60 unit^2.

The total surface area rectangular prism is 148 unit^2.

Step-by-step explanation:

Height of the rectangular prism = h = 4 units

Length of the base of the rectangular prism = l = 6 units

Width of the base of rectangular prism = b = 5 units

Rectangular prism = Cuboid

Lateral surface area of cuboid = L.S.A = 2 × h × (l+b)

Lateral surface area of rectangular prism :

L.S.A=2\times 4 units(6 units+5units)=88 units^2

Area of the base = l × b

Area of the base of the rectangular prism = 6 unit\times 5 unit=30 unit^2

Area of the two bases  = 2\times 30 unit^2=60 unit^2

Total surface area of cuboid = T.S.A = 2 ×(lb+bh+hl)

Lateral surface area of rectangular prism :

T.S.A=2\times (6unit\times 5unit+5 unit\times 4unit+4 unit\times 6 unit)

=148 unit^2
