solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$

Step-by-step explanation:

We need to solve the following expression:

$-8\frac{3}{4}-11\frac{1}{3}$

Solving:

$-8\frac{3}{4}-11\frac{1}{3}\\ =-\frac{35}{4}-\frac{34}{3}\\=\frac{-35*3-34*4}{12}\\=\frac{-105-136}{12}\\=\frac{-241}{12}\\=-20\frac{1}{12}$

So, solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$

Answer:

112 ft³

Step-by-step explanation:

→ Length (l) = 7 ft

→ Breadth (b) = 4 ft

→ Height (h) = 4 ft

Formula we use,

→ l × b × h

The volume of cuboid will be,

→ l × b × h

→ 7 × 4 × 4

→ [ 112 ft³ ]
