Answer:

V = 115.3 ft³

Step-by-step explanation:

The left part of the figure shows a cube of side length 4.2 ft. The volume of a cube is V = s³, where s is the side length. Hence, the volume of this particular cube is V = (4.2 ft)³ = 74.088.

The volume of a pyramid is V = (1/3)(base area)(height).

Here V = (1/3)(4.2 ft)²(7 ft) = 41.16 ft³.

Summing up the two distinct areas, we get V = 41.16 ft³ + 74.088 ft³, or

V = 115.3 ft³ after rounding up to the nearest tenth.

What is the rational exponent?

sergejj [24]

Answer:

Step-by-step explanation:

A rational exponent is made up of the power on the radicand (the number under the radical) and the index (the number that sits in the little bend of the radical sign). The rational exponent uses the power as the numerator and the index as the denominator. Even though you do not see any power on the 6, it is understood to be a 1. So rewriting this radical as an exponent is

$6^{\frac{1}{11}}$
