• Volume of a Rectangular Prism: V = lwh

Step-by-step explanation:

Step 1: Define

l = 7.8 m

w = 5.1 m

V = 110.1 m³

Step 2: Solve for h

1. Substitute [VRP]:                    110.1 m³ = (7.8 m)(5.1 m)h
2. Multiply:                                  110.1 m³ = (39.78 m²)h
3. Isolate h:                                 2.76772 m = h
4. Rewrite:                                   h = 2.76772 m
5. Round:                                     h ≈ 2.8 m

Answer 2

Answer:

A) 2.8 m

Step-by-step explanation:

The formula for the volume of a right rectangular prism is:

Volume = Length × breadth × height

We can just put in the values that we know to find the height.

110.1 = 7.8 × 5.1 × height

height = 110.1 ÷ 7.8 ÷ 5.1

height ≈ 2.8 (rounded to nearest tenth)

Thus, the answer is Option A.
